post #451 of 7924
Got my 5660 in on Saturday but have been swamped so haven't installed it yet. With my current chip i7 930 I have gotten it stable at 4.0ghz with memory at 7-8-7-24 1522mhz or so. (Corsair Dominator 1600 c8) The max bclk I could get with this config is 191 I'm using an eVGA TR757 SLI LE mobo by the way throwing way more volts at it (I'm at 1.325v) didn't seem appealing so I'm hoping that I can get at least 4.0 at a lower voltage from my 5660. I'll let you guys know as I get it installed and tuned today or tomorrow.

Is it harder to get to 5Ghz on LGA1366 6 core compared to LGA2011 6 core?

I have a X58 SLI. Should I stick with my 920 D0 or get a hex core for about $150?

This is what I'm trying to figure out too. I've been looking for batch info on the x5650 to make sure which to get. I'm also wondering about single core performance. A lot of the benchmarks that are listed are heavily threaded, of course that's going to look good with a 12 thread processor.

I'd like to see how a 4 ghz x5650 stacks up against a 4 ghz i7 920. Im going to look through this thread, but it's so huge I don't have time to do it right now.

That sounds good. If the RAM matches the configuration you already have then it'll probably work. I rarely [actually never seen] see 1600 RAM that didn't work. If id doesn't then you might have to do a little tweaking, but nothing major.

I have the cpuV at 1.2750v,, QPI 1.2975v It is prime 95 blend stable 50c 6 cores.
8-8-8-24 1n was too tight so I tried loosening the timings and that made all the difference
Folding at home 100% loaded it is at 52-54c

I will let it run a couple days and see how it looks.
Thanks

Your temps are good as well. I've peaked at 52c in the last couple of days. I'm running 4.2Ghz 1.275-1.28v now. I'm running my RAm lower than the rated frequency for good temps, low voltages and performance.

Do yourself a favor and upgrade to the Hex-core. That i7-920 is going to choke on high end AAA games. My i7-960@4.1Ghz bottlenecked my build along with GTX 670 2 way SLI. Otherwise you can stick with the budget 920.

Single Core? Everyone is going to use all of their cores and look for the overall performance. I did a single "Single Core" for one of my test [Cinebench R10]. There's a lot of things people are missing in my review. Some people don't know that I've benchmarked games and ran various GPU test. You guys should check out the entire review when you get a chance, not just the CPU portion. THe single cores in the X56xx [or Xeons-2 cores] has a turbo. I've actually listed several single core test. High-end X58 and X79 CPUs fails = Haswell-Z87-i7-4770K prevails in single core test. 4770K single core just owns everything from several reviews I've read since it was released. Overall performance obviously goes to Hexa-Cores and that's what people want.

Not everything is going to use 6 core though, so looking at heavily threaded benches exclusively may be misleading. I'm not saying your info is bad, I'm just wondering single thread performance to be able to see all sides. A lot of your tests are at extremely high clocks too, I don't imagine many of these cpus are going to get 4.6. That was why I specified 4 ghz. Games are largely gpu bound so there is not a great deal of variance.

I understood your post and took no offense. I was simply stating that I did indeed post one single core. The 4770K beats everything in Single Core tests so don't expect much in that area unless you plan to go Haswell Quad [you'll read that in a lot of reviews as well]. Some users here are hitting 4.2Ghz-4.4Ghz with no problems on the regular. My test were conducted at only 200mhz above some of their setups. My 4.8Ghz was solely to compete with the much faster and higher clocked X79 Hexa-Cores This was suppose to be mainly a Hexa Core review = X58 vs X79 High end CPUs and GPU\gaming results. I simply included my i7-960 comparisons for those running Quads and wondering. Some of the data [i7-920\960] was put there to compare with the L5639 as well.

Everything I've used so far personally has utilized all of my cores and that includes gaming.

I beg to differ. Throwing my Hexa-Core in the loop with Crysis 3 [and other titles] made worlds of difference as I showed in my Real Time Gaming GPU section. With the realistically high Quad Core overclock and 2 GTX 670's, I was only getting a stuttering 25-35FPS. Extremely inconsistent and was really not playable at all maxed out. I knew that my setup should allow at least 50fps 100% MAXED @ 1080p.

The moment I slapped in my L5639 @ stock [DDR-1333Mhz] the stutter issues were gone and playable. Performed a easy overclock and everything was smooth and I averaged 50fps easily. Now that I've put in my X5660 I have no issues with gaining frame rates and lowering my frame times. To think that the heavily GPU games won't get some really good benefits from the Hexa-core just isn't true from test I've performed with others with Quad cores. Same game comparison that I'll eventually get around to posting here and on my blog. 3.8Ghz is more than all you'll need for high-end gaming. Check out my Battlefield 3 GPU test. I'm going to get around to posting my Battlefield 4 test eventually.

I can run some 4Ghz test for you easily if you want. In CinebenchR11.5 I score a 10.41 with lower clocked DDR3-1400mhz RAM. I could knock the RAM up and tighten the timings to get better. 10.41pts is good for a minor overclock with a little trade off in the RAM department.

Alright guys. The temperatures have picked up here and the weather moving towards 26c and higher outside. I've finished my test and I'll post my temps here.

X5660 @ 4.2Ghz - Offset Vcore [Stable]

61 Hour Test [2 1/2 Day Test] - Temps and Voltage


Day Ambient Temp = 24c [purposely high for testing]
Night Ambient Temp = 18c

CPU Temp Max: 51c [100% Load]
CPU Temp Min: 22c
CPU Temp Avg: 27c [2 in a half days avg]

CPU Voltage Max: 1.28v [only when needed]
CPU Voltage Min: 0.96v
CPU Voltage Avg: 1.05v [yes only 1.05v average for a hefty 4.2Ghz overclock!]

I can deal with 27c CPU average on warm days. Running the A/C instantly knocks the temps down to about 24c - -25c during the hottest hours which looks much better. I think I might just let my build run like this for awhile.

Using Hex cores definitely makes the benchmark much smoother. The X5660 offered a 14.4% increase over my i7-960@4Ghz and only 2.7% over the L5639. Fire Strike depends on the GPU.

That physics score is insane, nearly 17000. My 920 at 4.2 with HT on got 10500.

Cinebench R10 is pretty old, but still useful. Well the Open GL isn’t that useful for me, but the CPU benchmark scores are. In the Multi-core test the Xeon L5639 actually does pretty well. The i7-4960X is 31.7% faster than the Xeon L5639 @ 4.1GHz and 71% faster than the i7-920 @ 4.4Ghz. The i7-4770K [Quad-Core] clearly outperforms the other CPUs core for core in Cinebench R10 Single Core. The i7-4960X is only X5660 14% better in the Multi-Core benchmark. I7-920 and i7-960 users will definitely see a lot of performance gains if they choose to upgrade to the X5660 or the L5639.

I downloaded and ran Cinebench R10 since you had some single thread results in there.

Got the x5660 installed today. So far I'm not able to get it stable at anywhere near the 191 bclk I had on my i7 930. I've had it at boot to Windows at 4.2ghz (cpu-z showed a 23 multi and think 184 bclk but running ibt immediately blue screened. I've thrown as much as 1.312v at it but have heard these 32nm chips don't eat up voltage like the 45nm Bloomfield so not sure if I should go higher?

Well I am running 2-Way SLI so that helps. The X5660 just gives the GPUs more than enough.

Oh so you finally found my single core test in the review eh? :thumb.gif:. I probably should've used CinebenchR11.5 & Cinebench R15 instead of R10 single core. I'm sure I still have my L5639 Single Core score for R11.5+R15.

As I've said the 4770K just smashes everything in single core test across the board. It's very efficient and is 52% quick than your i7-960. Your single thread is quicker than the L5639, but the L5639 has more cache and more cores so it wins by default [and even at a lower clock than the Quads].

All thought your i7-920 is faster than the L5639 in the older CinebenchR10 test the L5639, the L5639@4.1 stomps it by 34% overall making it more efficient period. [multi-core = complete CPU, not just one core].
Hey post your CinebenchR11.5 and R15 single scores as well. Can I get your RAM timing CPU-Z shot as well?

I hate to say it, but the budget i7-920 days are over [and have been over for sometime now thanks GPUs that need more]. With more efficient and Hexa cores available, $150 is simply a steal for all of the benefits you'll gain, but if you want to feel good about your i7-920 that's fine as well. My old i7-960 was great Quad, but is simply not enough. I'm just happy I can lift that Quad Core bottleneck off my system. The Quads simply CANNOT handle high end setups for gaming and other high end tasks I run on my PC. There's so many reasons why they can't as well. I can never vision myself going back to Quad cores.

They usually don't eat up voltage until high clocks, but every CPU is different. You might have to check some other settings. Make sure your RAM timings are good and check other voltages as well. Once you hit the 4.2Ghz speed sometimes you'll have to feed more voltage into the CPU. 4.2Ghz - 4.5Ghz really needs a decent amount for some people. Since you are running x23 I'm guessing you have EIST+Turbo turned off. Are you running C-State functions as well?
