Kuma Overclock Project - 3.0ghz

Hello! I am new around here, and joined up because after 7 years of PC building, I am ready to start my first overclock project. My aim is a modest one, but one I feel is sufficient for me (at least for now
).

I have done a lot of reading around here thus far and have gathered a ton of info from various posts. From what I am reading, I should have little to no trouble going from the stock 2.7 to 3.0. Unfortunately, I am unable to keep it stable and am unsure as to why.

I believe my motherboard might be partly to blame. It's a mATX board based around the 780G chipset. I can find the multiplier easily, and adjust it, but even up to 2.8 and sometimes the PC freezes.

My mobo has a bios feature called "Vcore overclock" which I am assuming is my CPU voltage (maybe its called "CPU Overvoltage"... I forget at the moment). It doesn't let me input exact voltages, just three options:
  1. +50mv
  2. +100mv
  3. +150mv
Is this what I am looking for? I tried going with +50 and CPUz reports my CPU voltage at around 1.38-1.4 after I do that, so I was pretty sure I had the right setting.

Even after accelerating the voltages, the multiplier still would not budge and remain stable. I doubt a heat problem is there because I invested in a good cooler for the chip knowing I was going to be overclocking. That is where I am at now.

For the record: my ram for some reason started stock at 5-5-5-15... even though it is rated at 4-4-4-12. So I made that adjustment (to 4-4-4-12) @ 2.2v (rated 2.0-2.1).

I need some more ideas, as I find myself running out of them! I cannot post screenshots of CPUZ until I get back home from work.

hmm that's wierd. you should be hitting 3.3ghz with that cpu by with just a simple multi increase and a voltage bump. since that cpu has a stock voltage rating of 1.25v ading 150mv should be giving you a total of 1.4v. that voltage setting is more than enough to get you past 3.3.

and since you've got yourself a decent cooler, you don't have to worry about overheating since that cpu can tank voltage above 1.5v.

also try to increase your northbridge volts by a tiny bit. with those settings, you can easily get passed 3.0ghz with just a multi increase. let us know about it. good luck

Maybe I will try +100 and see what that does... and see where my CPU voltage is from there. I thought I was going to get an answer like yours from what I've been reading about the ease of overclocking this thing...

just don't be scared to go all out 1.4v. it's still far from frying your cpu.


i think you can even reach 3.0 with stock volts at all. try the htt mode. set bus to 223 and multi to 13.5

Just so I am clear, define for me please HTT mode. I had tried playing with BUS speed by putting it at 210 and lowering the multiplier, but that didn't work either. I will try your suggested settings though and see what I come up with.

Roger on the voltage comment, its my number one worry! haha

yeah htt (aka bus/fsb) is increasing it instead of just using multi. can you also link me to your ram?

I believe the RAM is discontinued...Model F2-6400PHU2-2GBHZ

hmm all components seem to be well, i just don't see why it's very hard to get that thing past 3.0ghz. i know it maybe silly to ask, but just in case have you already disabled cool and quiet, and any spectrum related settings?

Have you tried to lower your ram divider from 800 5x to 677 4x?

Cool n Quiet is disabled, but I am unsure what is meant by "spectrum"?

And I haven't tried the RAM divider either, I will have to give that a shot. I spent all night updating windows and installing all my programs and apps (took FOREVER) so I didn't have a chance to mess with this last night.

I run 3.2 by bumping voltage to 1.375 and multiplier to 16, nothing else.

Well my bios doesn't let me just "set" a voltage. It gives me options:

Processor Voltage: either +50mV, +100, or +150. And TBH I am not even sure on the stock voltage on my board (or this chip, whichever statement is more accurate).

I am trying a multi of 14, and it won't run stable! Tried again last night and no dice. I diabled Cool N Quiet, and disabled C1E. Is there anything else I should be looking at?! I am trying to OC (a modest) 3.0, but I can't even get to 2.8 without having stability issues.

I use CoD:WaW to test stability. I know it isn't the best ever but when I can play the game fine stock... and then experience crashouts in the game after I try to OC a tad, that's enough for me.

Read this again, and have some issues/questions with it.

First, when I bump Proc v +100mV, it reads 1.48 (thereabouts) in CPUz. This is a bit high compared to your post saying +150 should be 1.4. Is there any reason this could be happening?

Second, I have a "Chipset Over Voltage" and a "Processor-NB Voltage". I am assuming the NB is the correct one but I wanted to make sure. Both have the same +50, +100, +150 options.

Cavi, what is your stock multi? you should easily be able to get 3.0 I can get up to 3.3 not 100% stable "Stock" but it boots up and runs without a voltage increase on my Board the big brother of yours, I would try to bump up the Multi up .05 from stock and go from there to see if it boots, you might have to bump up your CPU /NB voltage a small amount set your ram down to 400 or the lowest setting , try not to bump up your FSB so far to begin with I have some issues over 210 for most Multi and others Multis I can push it to 221fsb I would try 205 to start off with.

Stock multi is 13.5 (13.5 x 200 = 2.7ghz)

The PC will boot at 3.0 it will just freeze up after awhile (5-10 min).

I have disabled c1e and CnQ, is there anything else I should be looking at to disable?

that's really odd. unless your cpu has a stock of 1.35+. but i doubt it. 1.48 should put you above 3.3ghz already. maybe you just have a bad but working mobo

disable anything related with spectrum.

Ok, just updated the BIOS because one of the revisions said something about working better with some memory, so performed the flash without issue.

Now, I am running the CPU completely stock at this point, open CPUZ, and the voltage is reading 1.4v

I am going to see what the BIOS info tells me it is running at (if it tells me).

BIOS HW Monitor reports CPU running at 1.392v (1.4) STOCK. Without me touching a thing except my memory. Would another app, aside from CPUZ, tell me anything different?

Also, what is CPU Pre-Fetching? I don't know what it is, but it is enabled.

I also see nothing anywhere in my BIOS about "Spectrum"

Thanks everyone for the help so far, it is much appreciated and although I have yet to make any real progress, I have learned A TON from all the comments!
