[Solved] First time OC'ing - AMD Athlon X2 7850 Black Edition Kuma 2.8GHz

Like the title says this is my first time attempting an OC. I looked at all the stickies but didn't see the information I seek.

* RAIDMAX SMILODON ATX-612WBP Black 1.0mm SECC Steel ATX Mid Tower Foldout MB Computer Case With 500W Power Supply
* BIOSTAR TFORCE TA790GX 128M AM3/AM2+/AM2 AMD 790GX HDMI ATX AMD Motherboard
* SAPPHIRE 100258-1GHDMI Radeon HD 4850 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX
* AMD Athlon X2 7850 Black Edition Kuma 2.8GHz Socket AM2+ 95W Dual-Core Processor )
* G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit
* Western Digital Caviar Black WD6401AALS 640GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive

It would seem that if there is a bottleneck for most of the applications I use or games I play that it would be the CPU.

Looking to juice up the CPU, where do I go from here?

I am at a novice at OCing, but I did have this same processor except it was a X2 KUMA 7750 BE@3.2GHZ,2.7ghz stock w/ DDR@ 800@900Mhz The bottleneck was the cpu no matter the oc I just couldn't get it to Play games, without a lag. I just went and bought a X4 940 BE 3.0GHz stock no OC It seems to have opened the system up alot no lag. All games play silky smooth on high and very high settings i.e Crysis, I get 42 fps on very high settings now was getting less than 20fps before on high. I don't know if your a gamer. I just assumed it since the high quality video card. I hope this was helpful in solving your problem.

I had the same problem OverClkr with the 7750 BE even with it at 218 On HT Ref. in Bios with 14 multi I believe, anyway I had it clocked to 3.25GHz and it still wasn't up to par. Not in anyway was I contradicting you OverClkr and I hope u do not take offense I was just adding another 2 cent worth.

Yes, as long as you stay at 3.1Ghz, if you decide to go higher give it at least 1.35/1.36v .....

My 7750 was always reading 1.38v-1.41v without fooling with any type of overvolt using cool n quiet it went from 1.14v at idle to 1.38v-1.41v on its own

I appreciate the tip OC did not know that!!! You just saved my CPU from damage I thought something was up since I was supposed to be running 1.35V constant according to AMD OverDrive

Ok so I tried a little experimenting with AMD Overdrive.

I upped the multiplier incrementally to 15.5 incrementally and couldn't keep it stable. Tried with the voltage at 1.325(Stock) & 1.35.

Had no problems at 15x with 1.325.

What's my next step? Do I just accept that?

I am now realizing that even as I up the target Voltage to 1.35 that the current voltage doesn't move, still at 1.325. Is that something I might need to fix directly from the BIOS?

I have a 7850 BE and a ASrock 790GX MB, all I had to do was F2 to Bio's and turn the ACC function from Disabled to Auto then run the OC tuner and popped it up to a 15.5 multiply the voltage auto adjusted and it's running stable.


I keep reading about people trying to unlock additional cores on this chip and I don't think that possible?
