Q6700 Oc

[Sh0ckerNXT]

has any body passed the 3.6 mark on a 790i ultra without a bsod? if so how and ill share what i have learned thanks.

Well, what kind of cooling do you have?

[jellyrole]

If have something better than stock, you might want to try upping the vCore voltage a little bit. Also make sure you have set the voltage on your RAM manually.

Well we need to know your voltages.

RAM should be kept at stock voltage, timings, and speed, and set to "unlinked".

Open up Coretemp and tell us your VID. That is usually a good judge as to how much of an overclock your chip is. The lower the better (1.3 is bad, 1,2 is incredible).

For me, my Q6700 has a VID of 1.275, and takes 1.42 volts for 3.6 ghz.

how is 1.325 bad ?

how is 1.325 bad ?

The VID is the "stock voltage" the chip runs at, usually.

Now this isn't 100% accurate, more like 70%, but the lower the VID the better the voltage scales.

My 1.325 VID; X3220 (Q6600 Xeon) could only do 3.4 ghz with 1.5 volts.

Some 1.2 VID Q6600's can do 3.6 ghz on only 1.3 volts!

I have heard of 1.325 VID chips doing great, but I have never heard of 1.2 VID chips doing poorly.

i have the q6600 e0 stepping @ 1.325 vid and @ 1.4 i am doin 3.6 @ 1.5 i do 3.8 . it still greatly depends on mainboards and cooling .

I agree. I find that many users of chips having a vid of 1.325 or in that range just do not have a adequate setup to either have power stability such as load line calibration or a proper cooling setup or a good cooling setup with bad seating.

Like I said, there are exceptions.

But all overclocking is up in the air, some chips do better, some do worse.

Any luck yet Sh0ckerNXT?

Heres what i have come up with at Chips VID is 1.275

1400FSB@1.48 i can achieve 3.5 stable
1640FSB@1.50 i can achieve 3.6 kinda stable

This is with all setting on auto except FSB @ 1.4 and vcore of coarse

with the cpu OC'ed to 3.6@1640 FSB i have bad ram stabilty even with ram underclocked @ 10-10-10-28-2t its bsod

but at 3.5@1400 FSB its stable 24 hours prime. now i can't go any higher then 1400 not even 1401 or it doesnt post at all and i have to Cmos jump.

so it looks like im at 3.5 1400 fsb for now till i figure out this fsb hole more voltage info here

1.5vcore
fsb auto 1.4
mem. 1.9
spp auto 1.4
mch auto 1.5

gtlvref
+110
+80
+110
+80
And the cooling is Swiftech 220 Ultra on the cpu only idle 28c load 41c

divide that number by 4 to get actual fsb .. ( nvidia uses the quad pump fsb ) what is the mem running @ speed wise and what is it . also you may need to increase the nb volts up a bit .. mch-fsb setting ( i believe thats the one )

i have tried all settings linked unlinked even synced i have tried it overclocked underclocked i have tried it a 12-12-12-30-2t but when cpu is at 1640@3.67 ram wont pass any test no matter what i set it to it is corsair xms3 ddr3 right now im stable at 3.5@1400fsb with ram at 1440 fsb 7-6-5-18-1t but i want it stabvle at the higher fsb but its not happening for the ram:icon_tiphat:

[Sh0ckerNXT]

Now im at vcore 1.5000 3.67 1600 FSB linked and synced ram 7-6-5-20-cr1 trrd 3
