Some overclocking tips for the 1090t

post #1 of 9
Thread Starter 
So I have the following build set up currently and I was wondering about some things:


Phenom II 1090 T (I assume setting to a 20x multiplier is in order)
Corsair H70 (push/pull into case)
ASUS M4A89TD PRO/USB3 AM3 890FX Chipset
16 GB Corsair Vengeance (1600 capable) Mem
2x Radeon HD 6870 in crossfire
<http://www.newegg.com/Product/Product.aspx?Item=N82E16814121418>
775 Watt 80+ Bronze Power Supply (the name alludes me currently...)

Thermaltake case with some nice airflow on the VGA (230 mm side intake ~800 RPM) and CPU (200 mm top mounted, some incidental from H70 push/pull) (additionally 2 60mm VGA fans and I plan to mod the case as to add my 140 mm back into the build somewhere)
<http://www.newegg.com/Product/Product.aspx?Item=N82E16811133086>

some bluray player and 2tb hard drive...

I am aiming for a 4 GHz overclock with a 1.6 on the DRAM, and I wanted to know what kind of voltages you would recommend (CPU, DRAM, NB, SB?). Also I would like to slightly overclock the video cards if possible. Thank you in advance to all who reply

Well, you're going to have problems with that much ram, because the Integrated Memory Controller on the AMD Hexacores isnt good enough to handle it. You will propably have to increase Memory and CPU-NB voltages to get it properly stable.

Thank you for your response, but my question is recommendations as to the precise value of these parameters (I'm not so new to overclocking).

I'm sitting with my memory around 1600~ at stock timings, I have 1.46-1.48 voltage, I'm idling around 23-25c, loading up at less than 45, I have a push-pull configuration on the thermaltake frio with the stock fans.

I have a 210x20 setup to achieve 4.2ghz, stable on prime. Sig rig is up to date.

Well every CPU is different, so you should just start with multiplier at 20 and Vcore at 1.35v. If it doesnt boot or crashes in prime95 raise it to 1.375v etc. Repeat until you are stable. Max is 1.55v, and try to keep the socket temperature under 62c, but seeing you have water cooling I doubt that will be a problem.

wait for amd bulldozer, to be released o june 7th. it may be a bit expensive, but the 1090T will have at least a price drop by then

You can't really ask "what do I set my settings to for my own overclock", every piece of hardware is different aven if they are from the same family. Also if you not new to overclocking then you should know better than to ask such an open ended question about your own hardware.

Step 1. Find max stable bus speed (using lower cpu-multi) (only really need to get NB up to 3ghz)
adjust ram divider/ ht link divider. Set ht link to ~2400mhz
Step 2. Adjust northbridge clocks to ~3 ghz, will require a nb vcore boost. 1.3-1.4v
Step 3 raise cpu multi while upping voltage until you heat the heat wall. Back off a touch for 24/7 use.
