i dont have reboots on my dq6.overclocked 36%.But...i have Presler and Kingston hyperX pc 7200 memory..maybe its because of memory or something...so far so good...

Flashing to BIOS F4D seems to have fixed the clock control reseting and reboot loops. I can also boot no problem with >400 FSB. I cant say those problems will not return, but it seems better atm.
GAM, sorry I meant to say that vDimm was also set to normal.
I didn't know that 1.9V was preferred with the EM2s. Even at 800MHz? Anyways, I didn't have any issues with the XP2s. My problem with the EM2 could be because I overvolted them, or the BIOS did if vDIMM set to Normal.
There are so many variables!
Running at 8x375 FSB has been rock solid for me - dual Prime stable for 62 hours even when the heatsink wasn't making proper contact with the center of the CPU! On Tuesday I ran dual Prime for 16 hours just for the heck of it while running World Community Grid at the same time with no problems. RAM timings at 4-4-4-12 with these XP2s.
DS3 F5 (Final) + Presler @ 300FSB/3.6GHz (that's not much of an oc, considering the stock freq is 3.46GHz @ 266FSB)...
I'm getting random OC reset as well. It happens once in a blue moon, but when it does happen, the "Host Clock Control" will reset to Disabled and it'll go back to the default clock speed. It'll only happen when I've shut it down for a day or so and started it again. It's never happened no matter how many times I restarted the system, even if I turn it off, press the power button again to start it.
I've tested with both MemTest, Orthos and 3dmark05 over night and there seems to be no problem whatsoever. Been using this for 3 weeks, even completing Need for Speed most wanted without any problems. The only 2 problems I've seen so far are:
1) OC random resets
2) SATA drive random boot disk failure
These problems only occur once in a while. Does Gigabyte know these problems yet?
According to this, http://www.valueram.com/datasheets/KHX7200D2_1G.pdf, the SPD of your RAM is 1.8v. Now I don't really know what I am talking about here, but this is an indication to me that the RAM is 1.8v.Quote:

(I wish I had my board back so could be testing all this.:( )
Re EM2 1.9v. Refer to http://www.mushkin.com/doc/products/...ail.asp?id=373. Whereas, XP2 indicates a range of 1.9-2.1v. Refer to http://www.mushkin.com/doc/products/...ail.asp?id=350Quote:

Good news. Let us know if this changes.Quote:

As you know, 'Normal' vCore auto sets itself where ever it thinks is best. Probably better to set it yourself even at stock voltage if that works for you. 'Normal' mightn't be giving your CPU enough. I've had spontaneous reboots from Windows with insufficient vCore. (Don't mean to beat a dead horse ;) )Quote:

ZachSaw, what RAM?
Corsair ValueSelect 667 @ 800 :DQuote:

Someone should inform Gigabyte...

you dont have problems cause you dont use high FSBs ;)
there is so many threads of gigabyte mobos that we all already know that all models of gigabyte have reboot problems , sometimes boot with XX settings and next minute dont bot with same settings , ........ and other issues .
GUYS its NORMAL on all gigabyte mobos reboots, and other strange things , didnt you guys realised that yet???
regards
Everything is working fine with F4D so I'm sticking with it. :)Quote:

My HZ works fine at 1.8v, in fact more vdimm seems to hinder overclocking.
No dude....it is 2.0V to 2.2V.That's kingston hyperX ddr2 pc 7200 memory(900mhz factory optimal speed)...i advise you to avoid this RAM because of "elpida" chips inside, who are not good for overclock(sadly i have 2 giga of this ram)...Kingston pc 8500 hyperX(on 1066mhz) have "micron" chips that overclock very good....Quote:

Spec as per sig, F6a BIOS
random reboots over 400mhz on the 9x multi (was unstable but bootable with F5)
Exactly what RAM are you using (model nos.)?Quote:

1.8V for the HZ is cool for POSTing and making voltage changes...but has anyone tried to boot in Windows with 1.8V and 800Mhz?
Cause G.SKILL say it needs 2.0-2.1V for 800MHz, i run 2.2V to run at 933Mhz...pretty sure it good upto 1000MHz at 2.2V.
this one(2 giga i have):Quote:

This pdf applies to your RAM: Kingston HyperX Dual Channel DDR2 (PC2-7200): http://www.valueram.com/datasheets/KHX7200D2K2_1G.pdfQuote:

Sticker on my ram says 2.0V..not 1.8V;)Quote:

I am not doubting you, just trying to understand the difference between the various references to RAM voltages. Consider the subject dropped ;)Quote:

Board is getting 'repaired'-broken CPU socket pin, apparently. Getting very impatient for its return. 2weeks+. :( Apologies for not being able to contribute testing/info at the moment.
Best 'dual-prime stable' OC, before failure, as per sig. 'Decommissioned'.
It's ok;) .You are right...kingston forgot to put the range of voltage in data sheat from 1.8 to 2.2V:) .Thats the only thing here...Quote:

Oops. Sorry, screen shot and revision detail is for a different board (GA8i945Pro). Decommission sig details still apply though.Quote:
