I thought I replace the liquid cooler in the Alienware but the 3 I have don't fit. Hight is not a problem it is its wideness. Small room so a round pump fits nice. Seems they have thought about that :) Well then new thermal paste and the old stuff seems the be applied little. Now cool when running GPU (2) only, but quickly rising to 83°C when crunching on 6 cpu cores. I run now one at a time (at 75°C) and when finished I will replace once more another paste (the best I can get from were I work).

But I need (want) a new system soon and perhaps I can make a deal with the lady. However a question, I guess for Beyond (he will be smiling). I found an Asus Sabertooth 990FX R2 and a FX8350, together less than an i7 with 3.5GHz!
Enough space for 1 GTX690 or 2 GTX660 (with a slot free). I found Kingston blue memory 2 times 8Gb at 1600MHz. That works on the MOBO but I can not find on AMD's site if it works with the CPU. Will it?

Edit: I also see that the Kernel times (red) are high(er) on the Alienware than this morning when it ran with one GTX660, and the old thermal paste.

WUProp@home has more meaningful Results for both CPU projects and GPU projects:

WCG FA@H CPU comparison by app runtime

I suggest people buying a CPU look at their preferred project and the performance of different processors.


An example of some of the GPU data available:

GTX650Ti


GTX660Ti


GTX670

I would think that CPU & MB would work with most brand name DDR3 modules. Here's some info that might help:

I'd look into low voltage 1.35v DDR3 to lower power usage and temps a bit. From what I understand the FX8350 memory controller can handle memory voltages down to 1.2v.

BTW, nice system!

I found Kingston blue memory 2 times 8Gb at 1600MHz. That works on the MOBO but I can not find on AMD's site if it works with the CPU. Will it?

Yes, works perfectly. I have all 990FX chipsets with Kingston HyperX 1600 memory and no issue's. If you get that system, PM me or Beyond and we can help you with the BIOS settings (hope you don't mind me volunteering you Beyond ;). The FX8350 will work with memory up to 1866 and maybe higher with certain BIOS updates (native), and if you can locate a Sabertooth Gen3 R2.0 you get PCIe 3.0 (not much use yet).

Thanks, I will do that, but I think it will take a few months before the new system is ready to build.

While checking a few things I saw that the T7400 has 7 slots, only 2 PCIE that will needed but also with no space in between. Thus this large case is small after all and my mis-bought of the year. It is pointless to install a new PSU in it and will consider it as a loss.

Looking for a new case, they are all small or can fit a cooler with a height slightly under 15cm. The Cosmos II seems large enough but will not fit under my desk and is quite expensive.

Then the MOBO with space for two GPU's and space in between. Also tricky or they become expensive.
@Zoltan, as I see you have rigs with 2 GPU and I suppose you want a free slot in between, which MOBO's do you have that apply this? For a new Intel build.
Will go for the AMD with Sabertooth first, but just in case.

@Beyond, all I can find is Kingston 1.6 or 1.65V memory. It is possible that not everything can be obtained in the Netherlands. We dozens of shops and they have little from a lot of brands with a large price span. Sometimes I find stuff in Germany not all send it abroad. From the US can, but will be very expensive due to transport and customs, I have experienced in the past. Perhaps I can place a memory cooler as well. I saw some things from Zalman, to adjust all the fans from a front panel.

I would really try to find at least standard 1.5v memory. The 1.35v stuff is getting more common but maybe not there yet. As far as GPU spacing, you need two empty slots between the GPUs. That will give you a decent air space when using double slot cards. The sabertooth you mention has proper spacing for 2 cards.

Vagelis, sorry you went to all this work but these charts are obviously useless. They contain info from various apps over the years that are no longer used and had cell and GPU clients and apps that once had much higher credit awards. In some cases in the past cheating was commonplace and rampant. For instance, a core2 host in SETI or WCG running a GPU would score much higher than an i7 without a GPU. These charts include those cases. There is no useful information to be gained from these. Even a cursory glance reveals that they make no sense. Sorry...

Don't be sorry, it wasn't much work really. Besides, I believe you're wrong. What if credit rates have changed or some people were cheating? I believe it's pretty easy to single-out dubious results, like that Core2 or the old Athlon X2 and come up with valid conclusions. That's why I chose the top 20, so we have enough CPUs to work with, filtering out the "noise".

I went through the Yoyo list again, multiplying the single-thread Credit per CPU second (indicated by skgiven, thanks!) by the number of cores / threads in each CPU. I also removed the PS3/Cell entries.

So, here's the list for Yoyo:
Intel(R) Xeon(R) CPU L5638 @ 2.00GHz
Intel(R) Xeon(R) CPU E3-1275 V2 @ 3.50GHz
Intel(R) Core(tm) i5-2405S CPU @ 2.50GHz
Intel(R) Core(tm) i5-2550K CPU @ 3.40GHz
Intel(R) Core(tm) i5-3570K CPU @ 3.40GHz
Intel(R) Core(tm)2 Extreme CPU X9775 @ 3.20GHz
Intel(R) Core(tm) i5-2500K CPU @ 3.30GHz
AMD Phenom(tm) II X4 B50 Processor
Intel(R) Xeon(R) CPU E31220 @ 3.10GHz
Intel(R) Core(tm) i5-2500 CPU @ 3.30GHz
AMD Phenom(tm) II X4 B95 Processor
Intel(R) Core(tm) i5-3470S CPU @ 2.90GHz
AMD Athlon(tm) II X2 265 Processor
AMD Phenom(tm) II X2 521 Processor
Intel(R) Xeon(R) CPU E5205 @ 1.86GHz
AMD Phenom(tm) II N620 Dual-Core Processor

I didn't go through the WCG and SETI lists, since they can or have utilized GPUs and so the CPU numbers are not correct, as indicated by Beyond (thanks!). Besides, I didn't want Beyond to think I did so much work again! :P

Before you take a look at the Yoyo Top hosts list and dismiss the list above, please take into account this: This is statistical data for the whole population of Yoyo@home. Statistics is all about averages, means, medians and all that. By definition, single cases can and do exist outside the statistical domain. Also, we're discussing about CPUs here, not hosts. What would happen to Yoyo's Top hosts list if somebody with a dual Xeon L5638 system crunched for it?

The results are pretty clear, to me at least: Intel dominates Yoyo! Yes, if you own Yoyo's top or second top host, you may have a different opinion, but try to think about the general case: in general, Intel crunches better!

Finally, maybe some CPUs are overclocked, maybe credit awarding rates have changed through time, maybe some people have cheated, whatever. These discrepancies apply for both Intel and AMD CPUs, and therefore the final results shouldn't be affected, at least much.

I found this at Amazon: Kingston KHX16LC9X3K4/16X Arbeitsspeicher 16GB (1600MHz, CL9, 4x 4GB, DIMM 1,35V) DDR3-RAM Kit, so that would be okay.
Indeed the sabertooth is nicely spaced I will order that today as I see that their stock is going down.

Last night my Alienware shut down (I did set in Core Temp to shut it down when reaching 82°C. So the Arctic Silver is not good the the liquid cooling.
I will replace it later as the last Nathan is finished. CPU crunching is not possible now. Shame that I can't find a small CPU cooler with a fan that fit in the space provided. The MOBO is quite high mounted in the case to it will reach the top of it.

Greetings from TJ

Vagelis, your list has this Xeon L5638 @ 2.00GHz as the top CPU, yet it's really very slow:

http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+L5638+%40+2.00GHz

Your list has the i5-2405S @ 2.50GHz running faster than the i5-2550K @ 3.40GHz or the i5-3570K @ 3.40GHz. No i7 CPUs at all? What? Did you even look at your list? Seems not.

Pretty silly list, isn't it?

This is ridiculous. You can go through all the phony statistical gyrations you want but it doesn't make it true. Those of us who've run Yoyo for years know what CPUs produce the most. My teammate who was running all Sandy Bridge Intels saw how fast my AMDs were running and started switching over to AMD. He's the highest Yoyo producer ever. I'm number two. He's almost completely converted to AMD now. I admit to being an AMD fan. The cost/performance is better. In my experience they've been much more reliable (I've built hundreds of PCs for local companies and individuals). AMD has been the only thing that has kept Intel honest both in performance and pricing. Intel has played dirty pool against competitors throughout its history with it's FUD, anti-competitive practices, rigging benchmarks, giving payouts to PC makers to not use AMD, etc, etc, etc. . At least post a disclaimer that you're an Intel fanboy.

Here's the all time Yoyo leading machines. AMD dominates Yoyo (14 of the top 20 single CPU computers). Yet as you say there are MANY more Intels being used. How do you explain (twist) that?

Hi Guys, can we please keep this thread about hardware? That was the reason I started it. Okay CPU is also hardware, but please start a new thread about CPU comparison. Thank you.

And to the hardware. I have use other heat paste on the Alienware. It has now one GTX660, running with 93% load at 74°C and 74% fan speed (maximum). Perhaps to thick? The stuff did nice flow smooth from itself.

But worse it is now crunching one Nathan and 2 Rosies on the CPU. CPU is between 69-80°C. So I guess the Alienware will soon die. It will Kill itself or shut dowm when 82°C is reached.

The other GTX660 is in the other box (with all the problems with the first card) and does a short run now. It seems to be the same problems as before. Kernel times are almost the same as CPU usage. So when finished the GTX660 goes in the box and I put the GTX285 back in do some MilkyWay.

Then the Thread should be renamed to GPU Hardware Questions. So it is legitim to talk about CPUs in a HARDWARE QUESTION Thread in my opinion :P

Something is wrong, is the HS/fan seated properly? I'd drop the CPU WUs until you get it worked out. You could also try opening the case and aim a fan at it for now.

With NV 6xx series GPUs the CPU time is supposed to be almost the same as the GPU time. It's hard to say more when your computers are hidden...

[quote] TJ, when you asked the magical question: "What CPU would you suggest?" all heck broke loose :-)

I know, I did, but that is sorted out now. The sabertooth is on its way so...
But a long discussion about statistics and comparing things with each other that are not comparable, makes the thread long. Mercedes and Audi aren't comparable either.

Yes good seated, I did already set a fan besides it. And I found a small cooler, will order it and hope it fit.

I agree, there is probably a bit too much about CPU's in this thread already, and I get the feeling plenty of people want a better place to discuss CPU's further, so I started a new thread, CPU Comparisons - general open discussion :)

FAQ's

HOW TO:
- Opt out of Beta Tests
- Ask for Help

A question for system builders.
I have read some manuals about applying thermal grease to the CPU. A big drop in the middle and then spread out with an old bank card. Is that indeed what you do?

I have it spread very evenly in the past with the syringe it is in. The more expensive stuff then automatically flowed out like one smooth surface, but could be thick.
In a movie I saw that after spreading it out with the bank card that you could see the metal again. Is that okay?

I ask this because I get some coolers tomorrow and hope one will fit on the Alienware to replace it not functioning liquid cooler.

Thanks for the info, really reading with high interest.

More questions will follow in the coming days...

I've read the same stuff and tried a lot of ways myself. What works for me is to apply a thin layer to the whole surface of the CPU then put a rice sized drop in the middle before attaching the HS/fan. Sometimes it takes a few days before optimum temps are reached, but it should be close to target from the start. If not, the HS/fan is probably not seated well.

Except the rise drop we do it the same. I have got stuff from the cleanroom from the Uni where the use it with chips they made themselves.
However I forgot a liquid to clean the old grease. I have used white spirit in the past, but that is not good as I have read correctly. Personally I don't believe in all the special products that are sell for it. Expensive for "normal" chemicals found around the house.
What do you use Beyond?

P.S. the sabertooth arrived, nice board.
