Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

2 hour small FTTs pre-test PASSED :)

I'll run blend and if it passes 2 hours, I'll let it keep going for the full 8. I figure that might save some testing time!

**lukevega** · 09-20-2014, 09:59 AM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

2 hour blend passed! :D

Gonna' go with the flow and let it keep running for another 6 hours...

**lukevega** · 09-20-2014, 03:58 PM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Whoop whoop! 8 hour blend passed! Go turbo! :D

I will run Large FTTs overnight for 8 hours and then small FTTs tomorrow morning if all goes well. I'm really hoping I can build on these settings and get closer to that 4.0 and even the elusive 3.85 but for now I hope they can tackle the dreaded large FTTs for 8 hours!

**lukevega** · 09-21-2014, 01:39 AM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

8 hour Large FTTs passed also!

I'll have 30 mins of using the system and then start the (hopefully) final small FTT test.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Nice to see that you're making progress with LLC enabled and MCH Ref set 2 steps lower than the default setting.

**lukevega** · 09-21-2014, 10:34 AM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Some long-awaited success!

8 hours of small FTTs passed :D

Should I change anything before running some 2 hour 3.85 pre-tests?

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Tried running the same settings at 3.85 but no luck:

I'm going to try raising MCH Core a notch to see if it makes much difference. I hope that's not a step in the wrong direction!

**lukevega** · 09-21-2014, 02:50 PM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

I think that may have been a poor choice since it failed almost instantaneously:

Oh well, no harm done!

**profJim** · 09-21-2014, 02:55 PM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Try raising Cpu PLL from 1.57 to 1.59 volts.
The highest Cpu PLL setting that I would use is 1.61 volts.

I'm surprised that tRFC = 52 is still stable in your successful tests with your memory speed running at 980MHz.
Set tRFC = 62.

Your memory might be stable with 5-5-4-12 primary memory timings.
I would NOT try the 5-5-4-12 timings with tRFC = 52.

HWiNFO reports Vcore = 1.296 with LLC enabled during your tests.
You might be able to lower Cpu Vcore from 1.3250 one click to 1.31875 or possibly two clicks to 1.3125 volts.
I would NOT try even lower Vcore settings until you reach your final overclock.

MCH Core that is too high or too low will nuke you every time.

**lukevega** · 09-21-2014, 02:58 PM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

I did have half of this 'extra special' memory tested by a pro you know! ;)

I will change tRFC and CPU PLL to your suggestions. Almost time for bed here though but if the test fails I'll post the results before I go.

**lukevega** · 09-21-2014, 04:59 PM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

CPU PLL 1.590V and tRFC = 62 failed after 42 minutes. (but hey it was more than 30 minutes!)

I'm gonna' head to bed but might get a chance to load up a test before I go to work in the morning if you can advise on a next step? If I was guessing I'd would try increasing Static tRead Value from 8 to 9?

**profJim** · 09-21-2014, 08:04 PM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Memset = 980MHz (490 x 2) and your bios template says 960MHz.
ET6 MCH Core = 1.22 and in your bios template it is 1.20.

Some strange HWiNFO information:

minimum Vcore = 0.624
minimum DIMM = 1.296
elaped time = 1:27:40

In post #592 you said: "I'm going to try raising MCH Core a notch to see if it makes much difference."
In post #593 you said: "I think that may have been a poor choice since it failed almost instantaneously:"
In post #596, MCH Core = 1.22, the same setting as you used in post #593.

Maybe you should set MCH Core back to 1.20 and re-test with the current tRFC (62) and CPU PLL (1.59) settings.

Yes, tRD = 9 might work.

**lukevega** · 09-22-2014, 01:22 AM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Jim you have the eyes of a hawk! The test ran for so long as I forgot to check on it for a while but I had forgotten to change MCH Core back to 1.2. I therefore re-tested at MCH Core = 1.20, tRFC (62) and CPU PLL (1.59). The system lasted 11 minutes:

I will try tRD = 9 before I go to work and see if that fails before I go.

**lukevega** · 09-22-2014, 01:47 AM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

No luck with the tRD = 9 settings either:

I hope I haven't missed something again with it being early in the morning here! What do we try next Jim?

**profJim** · 09-22-2014, 02:12 AM

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

I hate to say it but I think that you need to change DRAM Performance Enhance from Turbo to Standard and manually enter some of the memory settings.

Another option is further tweaking of MCH Reference and/or Cpu Reference voltages.

Years ago a few claimed to have positive results with CPU Clock Skew and/or MCH Clock Skew tweaks but there was very little information for these settings.

A last ditch option is to buy a Haswell system with a K-model cpu for overclocking. $$$
