How much voltage to you you think ill need to add if any, to get a 4.2 clock? I have it running at 1.5 right now with a 1.3NB (Edit) Man the amount of voltage you have to push into these things is insane, i had to bump it up from 1.5 to 1.5375 to get a 4.2, Its running Prime 95 blend right now its 7 tests in and only pushing 47c. Using the Corsair H100 Extreme that just came out in July, Not in push pull config either (yet), waiting on my noctua fans

Using that tweaker program, was actually the only way i could get 4.1 stable, had to push 1.5 on all power phases and force 20.5 on each one as well... after that ran prime 95 blend for over an hour without an error, Prior to that errord out in like the first 14 tests

Phenom 1090T is a pain to overclock for some people, more so then not. I'm currently running one and cant push it past 4.0 stable. Here are my settings and system setup below if you wanna go off it for testing MSI 890FXA-GD70 AM3 1.10 Bios AMD Phenom II x6 1090T x2 Crossfired XFX ATI Radeon HD 5870 1GB @ 900/1300 Corsair Dominator 16GB DDR-3 1333 (9-9-9-24 666.7MHz) CMP16GX3M4A1333C9 Corsair H100 Extreme Cpu Cooler Corsair Force 3 Series 120GB 2.5IN SATA3 6GB/S SSD x2 Seagate Baracuda 500GB 32mb 7200rpm SATA2 Coolermaster 750W GX Series PSU 80+ Cert (I know i should probably get something better to OC and run the system) Coolermaster HAF 932 x2 230MM @ 700Rpm x3 120MM, x2 Corsair H100 fans @ 2150rpm, x1 Coolermaster R4 Sicklestream @ 2000 Temps don't push past 49c running Prime 95 Large FTT (For heat) - 30 Mins Temps don't push past 47c running Prime 95 Blend - 30 Mins For some reason its showing on the SPD tab the timing it can use at 9-10-10-25, But i've also read to ignore that kind of reading and go with the manufac settings on the sticker for stability... I might be wrong. I'm sort of a noob when it comes to ram timings and voltage for it, which for mine is apparently 9-9-9-24 @ 1.6 CPU Multiplier x20 @ 4.0GHz NB Multiplier x** @ 3000MHz CPU-VDD @ 1.4875 (Was previously at 1.5125) CPU Voltage @ 1.510 (Was previously at 1.525) CPU-NB VDD @ 1.300 (Was previously at 1.350) CPU NB Voltage @ Auto NB Voltage @ Auto CPU PLL Voltage @ 2.224 (Was previously at 2.554, read about it increasing stability, by bumping it a bit from stock) DRAM Voltage @ 1.600 (Stock voltage apparently according to the sticker, but had to set it manually along with the timings because out of the box it wasn't running at 1.6v 1333MHz, or 9-9-9-24) HT Clock x10 @ 2000MHz HT Link Voltage @ 1.25 (My HT isn't overclocked, infact i under-clocked it back to 2000 from 2600 after a lot of reading and benchmark reviews seems more harm then good and less performance comes from your HT when its over 2k, I added .500 volts to it just to make sure it stay's stable stock is 1.2) SB Voltage @ 1.25 (Bumped voltage from stock to assure stability, no downside to bumping it a bit) -- Now if anyone reading this can suggest what i need to push to get my 4.1 stable then please do so. Because i can get it run stable for about 15 mins, and then get errors running Prime 95 Blend. Mostly the rounding error 0.5 expecting 0.4 etc. Settings below are for my 4.1 Clock CPU Multiplier x20.5 @ 4.1GHz NB Multiplier x** @ 3000MHz CPU-VDD @ 1.5250 CPU Voltage @ 1.530 CPU-NB VDD @ 1.350 CPU NB Voltage @ Auto NB Voltage @ Auto CPU PLL Voltage @ 2.554 DRAM Voltage @ 1.600 HT Clock x10 @ 2000MHz HT Link Voltage @ 1.25 SB Voltage @ 1.25 I'm assuming its either a bad 1090T chip, or my PSU cant handle it. But reading. People say the rounding error is from a NB/Ram issue if you're running the blend test. But that confuses me cause i dont error out at 4.0 and the temps are about the same

With fraps running i just ran a benchmark on a multiplayer map in Bad Company 2 (Yes i know online isn't the best way to get a benchmark) and i achieved 139 FPS for more then 70% of the map dipped as low as 52, 1920 x 1080 x16 AF x8 MSAA All high settings, and that's on my MSI 790GX-G65 board

I don't know if i can justify shelling out another $150.00 to get a 2% performance gain by running them in x16 x2 , But i would be curious to see for myself what performance / fps increase i would get. I ran occt by the way, 0 errors and the settings i still have

LIke i said was going with a coolermaster theme or i would have chose differently, but yeah v8 isn't the greatest.. I have it running at - CPU Multiplier - X19.5 CPU VID - 1.4125 NB Multiplier - x13 NB VID - 1.2500 Memory VDDQ - 1.500 CPU VDDQ - 1.432 NB Core Voltage - 1.100 CPU HT Voltage 1.200 HT Speed - 2000 NB Speed - 2600 Core Speed - 3900 Its holding at 53, and been running Prime95 for about 10 minutes now, gonna let it keep running while i am at work and that should be about 8hrs, wish me luck!

Little bit of an update still running it at 3.8 x19 CPU Multiplier 1.4000 , but i now havee my NB at x13 (2600) running at 1.2500 from x12 (2400) at 1.1000 Seems to be holding steady, kinda scared to go higher

Yeah last night i did some experimenting with my clock at 4.0.... ran pretty hot, i had to keep the AC on in my office just to keep it in the 55-57 range.... It ran stable for about 2 1/2 minutes on Prime95 CPU VID 1.4750 NB 1.3750 x20 CPU Multiplier x14 NB Multiplier Kept stock ram settings Like you said i would need better cooling to go higher, i don't really doubt that at all. I went with the V8 because i'm kind of going with a coolermaster theme, Otherwise i probably would have used a Koolance water cooling kit, or the Corsair H50 The temps inside my computer are very low as it is with this much airflow, but the CPU could definitley use something more, Any suggestions? Using Everest here are some temps at idle Temperatures Motherboard 24 °C (75 °F) CPU 33 °C (91 °F) CPU #1 / Core #1 33 °C (91 °F) CPU #1 / Core #2 33 °C (91 °F) CPU #1 / Core #3 33 °C (91 °F) CPU #1 / Core #4 33 °C (91 °F) GPU1: GPU Diode (DispIO) 34 °C (93 °F) GPU1: GPU Diode (MemIO) 35 °C (95 °F) GPU1: GPU Diode (Shader) 33 °C (91 °F) GPU2: GPU Diode (DispIO) 28 °C (82 °F) GPU2: GPU Diode (MemIO) 29 °C (84 °F) GPU2: GPU Diode (Shader) 26 °C (79 °) WDC WD3200AAJS-22B4A1 29 °C (84 °F) WDC WD3200AAJS-22B4A0 29 °C (84 °F) Cooling Fans CPU 2086 RPM System 772 RPM Chassis 772 RPM GPU1 2705 RPM (55%) GPU2 1357 RPM (31%) Voltage Values CPU Core 1.42 V +3.3 V 3.36 V +5 V 4.97 V +12 V 12.14 V +3.3 V Standby 3.34 V VBAT Battery 3.28 V

My HT is running at 2000, and my NB is at 2400 x12 Multiplier

Yeah sadly it is the C3, I lowered the CPU VID 1.4375 to 1.4.. As far as i can tell having it at 1.4375 did nothing but raise the temps. and i can run it stable at 1.4.... So yeah it appears max Overclock for this without serious cooling is 3.8 =/ Also the only voltage i changed at all was the CPU VID from 1.3500 stock to 1.4000 --- System Below -- AMD Phenom II 955 BE 3.2 (OC to 3.8) x19 CPU Multiplier x12 NB Multiplier raised stock CPU from 1.35 to 1.40 voltage, rest all auto/stock MSI 790GX-G65 Crossfire Ready MB XFX ATI Radeon HD 5870 x2 8GB Kingston HyperX DDR3-1333 9-9-9-24 WD 320GB 16MB Cache SATA II x2 Raid 0 Coolermaster HAF 932 Full Tower (x3 230mm x2 120mm) Coolermaster V8 Cpu Cooler Coolermaster 800W GX Series PSU +80 Amp LED Blue Cold Cathode Tubes x2 Acer V233H 23" Widescreen x3 (Eyefinity Baby) Windows 7 Home 64

Just an update, been running Prime 95 Blend for almost a full hour now, still max temp is only 52, and has yet to fail a test yet

Hey guys i just started getting into the overclocking scene again, currently running my AMD Phenom II 955 BE at 3.8Ghz CPU VID 1.4375 NB VID 1.1000 Memory VDDQ 1.500 CPU VDDC 1.464 NB Core Voltage 1.100 CPU HT Voltage 1.200 I raised the Core Multiplier to x19 and the NB Multiplier to x12 i left the FSB Frequency at 200 and just bumped up the CPU Voltage. I've looked at many threads with different opinions, but i decided to start my own. Do you think i should raise any other voltage right now? I've been running Prime95 on Blend for 29 minutes now using AMD Overdrive to see CPU Temp and it appears its holding at 52.5 to 53C on all cores.. My goal is to get it to 4.0 but i cant seem to find a stable combo or a starting point to work from to get it stable at 4.0 Any input would be nice And sorry for posting if i missed a thread that covers this Im using an Arctic MX2 Thermal and a Coolermaster V8 for cooling inside of a HAF 932 with 3 230mm fans and 2 120mm fans

What up guys and girls, Just signed up looking forward to being a part of the community, i finally got around to building myself the dream pc i have always wanted, And now i'm looking to overclock!
