Hey guys,
I have a FOXCONN WINFAST 6150K8MA with an Athlon 64 3000+ (Venice S939) cpu and 1gb or DDR400 memory
I have mangaed to overclock my system from stock (1.8Ghz) to 2.47 (275*9, DDR266 divider, HTT 3x, and set the timings manually on my memory.
Here is the thing, i have been reading that this cpu is capable of up to (and beyond) 2.7Ghz and whenever i hit a HTT of 280 the system does not post, but will hang and reset the HTT down to 200.
My temps are all fine, under 35C and all of my settings are below stock, (mem is running at DDR266 and HTT is 3x and running cpu-z and prime95 and memtest86+ i can not understand why my system will not pass 280?
I know people have gotten the Venice cores to over 300Mhz FSB so why can not I?
I have a few ideas, some being that
a) i am using the stock heatsink and fan(BTW i attemping to increase vcore by 0.025 and still nothing)
2) I am using a generic PSU (450W, came with FOXCONN TS-01)

However, in order to increase my speed which components should i upgrade to achieve best results?

Thanks a lot for all comments/suggestions in advance,
If you need any more info i will get it (i build comps, therefore i know and understand stuff :P)

Hi Darin,

I have an Athlon 3000+ Venice on an Asus A8N-E.
2.47GHz is what I have achieved on my setup without a vcore increase. Pushed vcore a step higher and managed a little over 2.5GHz.
I comfortably hit your 2.47GHz speed with the same settings that you have.

The K8MA is a via chipset. I generally refrain from generalisations but then via chipsets are not the best around for overclocking. I have not used this particular chipset, but someone here who has can give you an idea of how it performs with o/c.

I dont think heat is an issue so long as your idle temps are ok (mine does abt 25C at 2.5GHz, the CPu can handle much more than that though), so getting a better heat sink is not necessary, for now at least.

Power supply *could* be an issue, but there is no way of knowing unless you change it :P

2.4GHz from the 3000+ is more than enough reason to rejoice - it is as fast as the fastest AMD single core processor :)

Try temporarily dropping the CPU multiplier to something like 6x, then see how high you can raise the CPU frequency. This *should* help you to determine whether the board is holding you back or the CPU.

thanks guys but just to clarify my chipsrt is NOT a via chipset!
I am using an nforce 430/geforce 6150 chipset (i can not afford a graphics card right now, and this onboard is actually decent)
i will try to lower the multiplier to 6x and attempt to go higher
thanks and i will post again with my results

arrgh, sorry, my bad about the chipset.

oops! another mistake, typo this time.

(mine does abt 25C at 2.5GHz, the CPu can handle much more than that though)

I meant 45C at 2.5GHz.

I can only dream abt 25C idle! - in Bangalore where I stay (India), even in the peak of winter the air temperature is 20-25C during nights, only occasionally dropping below 20. 25C idle would be impossible with stock cooling (or even after market, for that matter!)

thanks guys but i think my board is the problem, which is odd because i have seem reviews of this board and a Venice CPU goingo over 2.6Ghz
Thanks for everything though, really apreciate all of the input

Did you try what jam suggested with the 6x multiplier?

yes i have tried what jam suggested with the multiplier and still a no go
i am tried raising vcore by 0.025 and still a no go
what is wierd is that i have read that people have gotten to over 300+ with this board and Opteron CPU's but i also hear that the Venice 939 are amazing at OC'ing
Thanks for nything
apreciate all the help
As always
