oc trouble, stable cpu, ram issue

jasoncourt · 20 May 2012 at 17:56

hey ppl. new guy jason here, ill get to the point tho,

trying to overclock my system, cant seem to get the ram to overclock to well,

system specs are:

i7 920 d0 stepping / asus p6t se / 2x2gb g.skill ram 12800 1600,hz / nvidia gxt 260oc / wd hhd

my current (unstable oc) is at 3.6ghz, with ram at 1804mhz, if i underclock my ram it is stable, my bios setup is as follows.

oc xmp

1600mhz 9.9.9.24.2n 1.5v

cpu ratio 20
speedstep dis
bclk 180
pcie 100
dram 1804

cpu 1.225v
cpu ppl 1.9v
dram bus 1.64v

and disabled
cpu spreadspec
c1e
virt
cpu tm
speedstep
cstate

also ive been told to BCLK to 200 w/ the multiplier set to x18 = 3.6GHz w/ the x8 DRAM mult. = DDR3-1600. but then my ram is stock,
if anyone could work out were my problem is, would be greatfull cheers jason

ok cheers, so what would be better,

cpu ratiox20 bclk180 with ram at 1440
or
cpu ratiox18 bclk200 with ram at 1603(bios came up with 1603)

i always got told higher cpu ratio is better,

cheers for the fast responce

As RJC has said, the ram will be fine at 1600mhz, as you overclock it youll probably need a jump in qpi/vtt voltage.

so say i leave it at stock 1600mhz, do my voltages look ok

so how do my other voltages look,

cpu 1.225v
cpu ppl 1.9v
dram bus 1.64v

cheers

RJC said:
You should be able to get 20 x 200 with the ram multiplier at 8x.

wouldnt that be 4ghz.. im on air coooled tuniq tower,

my idle is 45 and 15mins of prime hits 74c atm

jasoncourt · 20 May 2012 at 18:18

what bout the dram multiplyer, i think my temps will be to high for 20*200, whats the max i7 temp allowed?

jasoncourt · 20 May 2012 at 18:28

cheers, looks like im getting somewere, whats cpu imc voltage, cheers ppl

jasoncourt · 20 May 2012 at 18:37

ok ive done same as the pics, apart from cpu voltage is cpu 1.225v and qpi is a little higher than that, sould i be increaseing them? cheers

jasoncourt · 20 May 2012 at 18:40

oh blue screen, just inceased qpi and cpu volts to same at pics,

bluescreen was something todo with irq

jasoncourt · 20 May 2012 at 18:48

ok, so got the same setup as pics, and computer says no, it rebooted itself as i turned around. temps were at 82c when i last looked

jasoncourt · 20 May 2012 at 18:52

could it be going weird coz my pcie was set to 101. its alread overclocked edition?

jasoncourt · 20 May 2012 at 19:01

no im gna leave it ram stock, so

atm i have 20*200
dram at 1603
uclk 3208
qpi 7218mt/s

cpu v 1.3250
qpi v 1.33125
ioh v 1.2
ich v 1.2
dram bus v 1.66

should i be at 21*200? temps atm are max 85 with prime

jasoncourt · 20 May 2012 at 19:46

can anyone help. i need my pc for tomorrow and im stuck with a blue screen cheers

jasoncourt · 20 May 2012 at 20:24

ive backed the cpu to 20*199 so my ram is only underclocked a fraction, and increased vtt to 1.35 and now i get

dxgmms1.sys temps are hitting 87'c
