Timings:
RAM : 8192 MB DDR3 Dual Channel
RAM Speed : 933.3 MHz [1866MHz] (3:14) @ 9-11-9-27

Yeah. not much benefit from O.C. on NB or HTT. HTT should be stock @ 2600Mhz. The best results I've seen is to leave the HTT and NB @ Stock. Get the CPU Multi where you want it, or can get it stable. Since you are running 1866Mhz DRAM, you can bump the FSB to maybe 215 to get the DRAM around 2000Mhz (Set the PCIe Lane to 100 from Auto)

You probably wont have to adjust the HTT or NB voltages for this slight increase in Mhz, but what you will need to increase is the NB/CPU voltage which is the "On-Chip NB" voltage. This needs a slight voltage increase to improve on memory bandwidth, especially to get a stable O.C. on your DRAM.

You shouldn't have to change your DRAM timings @ 2000Mhz, cause it's not a big jump. (Oh looks like your DRAM is rated for 2000Mhz @ 1.5v. Lots of room then.

So I'm sitting at

4414.73 MHz (200.67 * 22) @ 1.45v

Utilizing a Corsair H100, I'm unsure of pushing it any further as I see that I'm getting reports of 67* C while running Prime95.
Any advice on what to do next or if I should leave it at that?

Room temperature is at 70* - 71*

My case is the CM Cosmos 1000, so cooling isn't too efficient as opposed to newer model cases.

I'm happy with the overclock in general but I have seen many others with the same setup push 4.7 - 5GHz
My current goal being that of 5GHz, though I would probably need better ventilation for that. Maybe even a better Water Cooling setup.

Finally got my v-core down. Not Prime stable but ran Aida64 for a few hours no problem. Hasn't crashed on me yet

400 401

Back down to 4.7ghz @ 1.46v, BF3 keeps crashing at 4.8ghz, my block cannot hold the temps. Still loving the CPU, put my 1055t up for sale.thumb.gif

Whoah? I hope your talking 70-71 Farenheit in your room.

Looks like you are doing pretty well with your O.C. I've done a bit of testing with the H100 as that is what I use as well. There are a couple things to watch for with it.
Make sure your fans are blowing through it, and not trying to draw the air throught it. Another thing to note is that it's hard to get the CPU block seated properly.
From your temps, that's what I suspect is happening (unless you are using poor paste) What what you can do to test this (**if you feel comfortable with it)
With the computer running a torture test of some sort, Prime95 is good. Lay your computer on it's side with the side panel off. Slightly loosen the CPU cooler on both sides.
Then as evenly as you can, start to tighten both. Because you are doing this in real time, you'll be able to see the Temperature swings, to know if you are doing it right.
AND to make sure it's not OVERTIGHTTENED

With your settings and good TIM, you should be sititng just under 50C at full load, with the H100


Here's a CRUDE picture of a bad setup.
350

Also, I think you should be able to drop your CPU Voltage a bit more for 4.4Ghz. Maybe 1.425

add me please. just got my fx-8120 installed and up and running.
post #4190 of 8112
Ahh, yeah that must be it. I was hitting 67 C when running Prime yesterday. I immediately stopped to have it cool down.
Also, yes I meant the room temps in Farenheit.

I'm using Tuniq TX-4 I went with it because of the recent Maximum PC review and wanted to give it a try.

Thanks for the advice, once I fix the mounting issue I'll double check the temps and then start messing with the Voltages again.
