I know personally that 3835A was really bad for me, and 3838B was not good either...

Check your private messages by the way :)

My 3844a has been one of the best I've seen for voltage and high clocks. Will do 3.6 @ 1.075v, 3.8 @ 1.145v. Temperatures are hard to keep under control though.

hi everybody i just got a new rig and wanted some help on my OC, looks completly diferente to what i was used to(p5q deluxe) anybody with a similer system as mine?

PS: what bios should i get?

can you pm me setting for a 3.8ghz oc..
right now all i can get is 3.5 ghz that is stable.. for some strange reason..

I am so lost. I've tried so many settings to get this stable at 4.2 and when I think I finally have it, 1 hour of Prime 95 gives me BSOD.

I'm a little scared of trying custom voltage, but have been up to 1.35 and still no go. I am using a multiplier of 21x200... Anyone can help out?

I can probably help you...I'll send you a PM.

ca you specify the vtt voltage or what they call that
do i leave that auto?

i have cpu voltage at 1.3v
qpi/dram at 1.35000v
dram voltage at 1.66v
dram freq at 1603 ddr3
qpi link speed freq at 7270mhz the only setting to choose from.

so as of right now i'm getting 3.8ghz stable atm running test right now temp at 77 around there for all cores
and i have this set at 200 x 19 1.3v

anyone know any other way to update the bios? my @bios is telling me to deactivate Dynamic Energy Saver but then says Terminate Dynamic Energy Saver Failed

Use Q-Flash. Download the BIOS file (only bios file .f5) and put it on a USB flash drive. Then, during the POST screen, press END and follow the instructions. I just flashed to version F5 today.

Well, I think I managed to get the system stable at 4.0 GHz after OC'ing for nearly 5 hours. Here it is:

Frequency.............................4.0 GHz
Clock Ratio............................20x
Bus Speed.............................200 MHz
vCore...................................1.344v idle | 1.328 v load --- 1.38125 in BIOS
QPI/VTT voltage.....................1.32v
DRAM...................................1.58
Uncore Frequency...................3200 MHz
QPI Link................................x36 (7.4 GHz)
Performance Enhancement.......Standard
Memory Multiplier...................8x
Memory Speed.......................1600 MHz

I realized that the vcore voltage was the biggest limited factor. Haven't tried to lower the DRAM/QPI voltages yet.

Questions: Do you guys think that my vCore voltages (1.344 idle/1.328 load) are safe to be running at 24/7? On 100% load, the temps hit 80*C and they are 44-46*C at idle.

Should I drop it down to 3.8 GHz where I had vCore at 1.216v idle / 1.20 load? Temps were about 5*C cooler...

Thanks for the input / suggestions.

Hello Everyone,

I can't seem to keep my PC Stable at 4.1-4.2. I keep trying but keep running into this wall...

My settings are:
CPU Ratio - 21
BCLK - 200
PCIE - 108
DRAM - DDR4-1603
UCLK - 3208
QPI - 7218 MT/s

CPU Voltage - 1.46250
QPI/DRAM Core Voltage - 1.35
DRAM Bus - 1.64
HT-Off
Everything else is AUTO. Not sure what my batch number is, but I bought it January.

I also tried 19x219 and still get BSOD. I am stuck on this ring and cant seem to get out of it. :-/

Check your PM again and definitely drop that PCIE OC. You should never OC your PCIE bus. Maybe by 1MHz or 2MHz if you really want, but generally no OCing of PCIE is recommended. I gave you a bunch more things to try in the PM.

You are okay with temps in the low 80Cs for 24/7.

I was a bit worried that I originally put too much thermal paste. I applied a layer to the entire cpu and spread another layer onto the bottom of my Thermalright Ultra-120. Did I overdo it? Could this be why my idle temps are about 43-45*C and not in the high 30's?

That seems like a lot of paste. Just a dot in the center and then let the weight of the Heatsink spread it out. Good luck OC'ing!

Also you could lap your True 120 and run a second fan (if you don't already).http://www.overclockersclub.com/guides/lapping/

Thermalright's instructions said a layer on both so I just followed those...

Would you recommend that I redo it or leave it as is?

Just wondering if my core i7 920 with noctua nh-u12p / 2 120mm fans, corsair dominators 6gb, asus p6t deluxe v2 can get 3.8ghz? I tried b4 with my aenon 3gb 1600mhz but couldnt get it to be stable but i went out and bought the 6gb dominators and see if it will make any differences..anyone with some advice?

need help with ocing my rig..
having trouble getting it stable at 3.8ghz.. 200 x 19 now im trying put the vcore at 1.35 and see if it works please give me some advice..

how come my asus p6t deluxe v2 dont show the memory multiplier and qpi link speed :S well it does have qpi link speed but shown differently than the one shown

Have you download the last Bios for the Asus P6T Deluxe V2 -> 0302 !! i run now at 3.930Ghz (19x207) with 1.25625Vcore in Bios.
3.8Ghz has enough with 1.1875V thanks to the new Bios 0302 .With the first one 0102 the cpu needed alot more vcore to reach these speeds!

Got a new problem with LinX, actually I don´t know how to use it, I just used all my memory 12gb and then started the app, however, it turned out blue screens so far.

First:
Driver IRQL not less or equal

Second, after raising the DRAM Voltage to 1,7:
system service error

Those are my basic settings:

Where should I start tweaking?

Add some vcore maybe? Isnt 1.23v a little low for 4Ghz HT on?

sigh I have the new 0302 bios as well..but i cant get it stable at 3.8ghz with HT on ...its stable now at 3.8ghz with ht off :(
