[Gigabyte Ga-X58a-Ud5] i7-930 overclock plateau @ 3.8ghz

After many days of reading forums, and reading the 3 step O.C. guide, I'm stuck @ 3.8ghz (i7-930). I ran OCCT for an hour w/o error but my temps max out at 78deg and 80deg produces an error.
I would greatly appreciate any help in fine tuning my settings to achieve 4 or 4.2ghz.

P.S. This is my first overclock build, and post O.C..

Thanks,

EWJ

Vcore is to low.
You'd need a good bit of luck to find a Bloomfield that will do 4 to 4.2 at that vcore (note in windows it will be lower again)

Hi to the forum.

Try my settings here, some have had success with them, others hav'nt: http://www.overclockers.com/forums/showthread.php?t=639976

Thanks for the input. I adjusted the threshold in OCCT for a 83c max settings, and my bclk of 182 maxes my temp out at 82c. I can overclocked to 4.0-4.2ghz without a problem, but the temp gets too high. If I set OCCT threshold for 85c, the 191 bclk errors out in about 8mins. Do you think its safe to be in the 85-90c range?

Been reading many helpful posts in here and just tried O'C my i7 930 to 4G. Did a quick test with IBT with maximum stress level and passed 5 runs. Temp is around 35-45 idle and as high as 75 when 100% loaded with RealTemp.

PC Config :
i7 930
X58A-UD5
Corsair 1866 2Gx3
Intel X25M(OS)
WD "Black Label" 1TBx2 Raid 0
VX + Wing 12 PLx2
Sapphire 5770(no games on this PC)

Bios setting :
Multiplier 20x
QPI Multiplier x36
Uncore Multiplier x16
BCLK 200
Performance Enhance = Standard
X.M.P. = Disabled
Memory Multiplier x8.0
Memory Freq = 1600
Load-Line Cal = Standard or Level 1(both OK)
CPU Vcore = 1.30v
QPI/Vtt Voltage = 1.295v
IOH Core = 1.30v
DRAM Voltage = 1.66v

I would like to o'c the RAM to 2000 too. But I did a very quick test and the PC just failed to boot. Will do more tweak when I have the time and run more stress tests.

Best way to overclock your ram is not to change the memory multiplier, as I have found with these new "A" series of boards, the only mem multiplier they seem to like is the x8 one which you and me both are using, but instead if your happy with your CPU a 4ghz, drop the CPU multiplier to x19 instead of x20 and then up the BLK again to bring your CPU back to 4ghz (19 x 211 = 4009mhz cpu), you will prolly need more NB volts and also QPI VTT to compensate for the extra blk, as you will be putting more stress on the board and also on the CPU's mem controller with the higher mem speed, etc etc,

Just keep doing this, dropping the CPU multiplier and upping the BLK 1 step at a time until your happy with both CPU and mem speed, just be careful with voltages and heat.

Seanie's Show, your posts in this fourm had been very helpful. Thank you very much for your help and sharing you info. Also, the 3 steps guide found here is an excellent read!

Well, just tried Memory Multiplier x10, Uncore Multiplier x20(4000 Unc Freq) and boost the DRAM voltage to 1.68v, QPI VTT voltage to 1.34v. Can't get the PC to boot into Win7 x64.

If I keep the memory multiplier at x8 and want to up the RAM to 2000, I would need a big jump on BCLK. Not sure if there's possible...or am I thinking on the right track here?

BTW, RAM is Corsair Dominator TR3X6G1866C9D 2Gx3 running at 1600mhz 9-9-9-24-2T currently with 1.66v.

Is it true that many people tune their RAM to run at lower speed to get a stable OC on CPU? In my case, it seems I have to set my 1866 RAM to run at 1600 in order to get a stable OC on i7 930 at 4G.

Think I could get one of you experienced guys with a setup like mine to give me your info and a little direction? I don't have to have it maxed out, but would like to speed it up some. This is my first time doing this.

Hello folks,

After 2 weeks of hardware tweaking, going back and fort to a computer shop nearby, staring at my temps, swapping heatsinks, applying thermal compound and reading tons of posts about achieving a milestone in i7 930........

I finally came to a point of success.

Tested these settings below on Prime95 using In-place large FFTs for 12 hours and my system has been stable.



IDLE TEMPS: (CoreTemp 0.99.5)

42-39-41-38

MAX TEMPS running Prime95 in-place large FFTs for 12 hours: (CoreTemp 0.99.5)

Hope this helps -

Just wanted to thank _s3v3n_ for their post. I have an i7 930 and GA-X58A-UD5 and your tweaks worked fine and got me to 4GHz.

Strange, I bought the system fom Scan Computers who claimed prir to purchase that they would supply the system pre-overclocked at 4GHz but after 3 days of hem messing with the system, they were only able to get it stable at 3.8GHz.

So a 2nd thankyou, you've done better than the pros and my system seems stable and getting good results from benchmark tests.

Ciao

I know this post is more than 4 years old. The settings that you have above is to OC it to 4ghz. What would I be tweaking to get from 2.8ghz to 3.5ghz?

This is my first post and I have been trying to find the answer to this for days now. I don't want to mess up the board so if you could help, would greatly appreciate it.

Thanks
