FX 6100 OC inquiry

post #1 of 17
Thread Starter 
Hey guys, just curious if I may be doing something wrong with my OC. Im trying to get over 4.6Ghz with my FX 6100 but seem to be unable to budge. Im using an H80 for cooling with a push/pull setup, LLC enabled in bios with all the extra C6 State disabled. Im only using the multiplier which is currently set at 23 and due to LLC being enabled I have my voltage set in the bios at 1.45 but when I run Prime 95 cpu-z tells me im hitting 1.54V-1.55V. Im wondering if turning off LLC would help me achieve a higher OC? any suggestions welcome biggrin.gif

Could I get better performance out of it if I dropped 2 cores and made it a quad core with higher clocks? I play BF3 mostly.

That really better for overall performance?? Never tried, but if its better I will.

Well thats what Im wondering.... I know Ive heard before ( I forget where) that BF3 only really utilizes 4 cores anyway. And I believe by dropping 2 cores I can achieve a higher clock with less voltage on the 4 remaining. But Im not 100% on that.

the 1.45 vcore that you see in the bios is your idle vcore.
Once the cpu gets to full speed, you should expect it to go higher so 1.54V is your full load vcore

Try lowering the multiplier a bit and using the bus speed to overclock further.
Something like 230 bus speed and 20x multiplier. It might get you 4.6ghz at a lower vcore

Ive never attempted anything but the multiplier, is there anything I should know about messing with that?

FSB/HTT overclocking usually gives better performance.

Only thing you need to know is that its basically the same as raising the multiplier but instead it raises everything else with it.

Just make sure these values are at stock if you raise the FSB
DRAM freq. So if your RAM is rated for 1333mhz/1600mhz make sure you change this because upping the FSB will up these also
CPU/NB, again make sure its at stock
HT link, usually rated for 2200mhz or 2400mhz sometimes 2600mhz on some boards, keep it at 2200 so you know it won't be the problem when overclocking.

You'll see the values change when you up 200 to say 220. Aslong as the values are below or at stock you won't have problems.
Up the FSB in increments of 10, so 210... 220... 230 until you fail to POST. If you can't post at say 250, try 245 until it will POST. This is your limit, then try there you can raise the multiplier as you usually would trying to find the best voltage for that OC.

FSB clocking is the same concept as multiplier except it changes everything tongue.gif so its a bit more fiddling to get everything

I use 990fxa - UD3 with h70 push-pull in zalman z9 case. Reached 5 ghz with my fx-6100 @ 1.575 v . currently IBT stable @ 4,85 with 1,5 volts (LLC raises 1.52 or around that) left HT stock @ 2600 , NB is at 2,2 ghz

CPU is 21.5x 226 @ 1.5 V.

DDR 1333 G.skill ram 4x4gb overclocked to 1500 mhz

Hope this helps with your overclocking.

You can also achieve a slightly higher multiplier overclock by raising the VDDA/PLL voltage, default is 2.5 but seen this increased to 2.8. Not the best voltage to change but it can give higher mulitplier

Ok well I'm in the process of doing this and noticed you can't make those things you mentioned stock. It changes as you increase the bus so my options are either under or over stock. What do you recommend? Also what about pcie and stuff? Just leave that alone?
