Hitting a wall with my 1090t?

post #1 of 14
Thread Starter 
I really haven't tried very hard with overclocking, but now with liquid cooling, I'm ready to get the clocks up.
I have it stable at 4.1, and I don't know if I've hit a wall or not. I've never asked for overclocking advice, but what the hell. It's overclock.net

I'd say 4.1 is pretty good for 1.5 volts. Bump the voltage and you should get around 4.2.

And please tell me TMPIN1 is your chipset running at 70C and not your socket temp or anything.

CPU is socket temp. Just remember that the Phenom2's throttle at 62 degrees and sub 55 is ideal,

you could try to bump the multi down to 20 and use the fsb and see if that helps get the very last out of it

EDIT: i recall reading somewhere that 1.55 is safe on the x6's as long as temps are in check

4.1 at 1.5v is decent

since you're under water, i'd say it's safe to bump it up to 1.55v , as long as your temps stay below 55c

i'm at 4.3ghz (21.5x200) 1.53v and it's rock solid, been folding 24/7 for weeks now, temp about 35c, +/- 4c depending on ambient

I'll start by saying, 4.1 is not good for 1.5. That kind of voltage will degrade the chip over a relatively short period of time. Thubans seem to be great or terrible for voltages, mine runs stable @ 4.0ghz on only 1.332 volts. I have no idea how good your ram is for overclocking (remember good ddr3 can handle a good 1.8volts and be safe).

***TRY THIS***
-set your FSB to 225 and adjust HT,NB & Ram accordingly.
-DISABLE cpu spread spectrum unless you plan on setting it by a microwave.
-Disable PCIE spread spectrum (only while stabilizing OC).
-If your MOBO supports it, or something like it Enable Load line calibration. Vdroop is the reason why most Oc's fail the moment the cpu begins working.
-After all this start with a multi that gives you 4.2ghz, @ a voltage of 1.45. Load up and run an intel burn test on High Stress. If you pass it go back into the bios and lower voltage... Continue until Intel Burn fails.
-Once you have found a good 4.2ghz try for 4.3 or 4.25 and keep upping the voltage until you pass a burn test.

Also the lower the NB & Ram Oc the more room the CPU OC has to stabilize, however Nb overclocking to atleast 2600-2800 will show the most real-world gain. Ram is good @ 1333 for gaming, 1600 for benching with the best possible timings. HT ALWAYS @ 2000mhz. Feel free to pm me if you need help.

The RAM at generic timings is holding you back, though as far as I'm aware most OCZ Platinum are not generic timings/speeds. Set your RAM correctly and see if you can go further.
EDIT: NVM, you have a 1090T. Though you should still set your memory correctly, sometimes high multipliers will crap out but the same speeds can be reached by overclocking the bus clock and using a lower multiplier.

how about some proof for these two statements?

x2. Took me right around 1.5v for 4.1.

To OP; as long as you keep temps below 62C then you can increase your voltage up to 1.55, some say 1.6v is safe for water; but I always stuck below 1.55 to be safe.

QFT
after stabilizing my OC i booted up ARMA2 and ran the built in benchmark and was hitting 50 fps with the auto settings, next day i remembered my NB and upped the multi so its now 2800 and i gained 10 frames, more then i gaind from 3.6 -> 4

I'm also topping out at 1.5v at 4.1. I really have hit a wall, though, since my 1055t won't do 4.2 stable even at 1.6v.
