Sempron X2 190 Can't get 4.0GHz - Page 2

post #11 of 36
step your multiplier down to like 7x

and then try running those insane FSB's again.. try to see the overclock limit on the FSB on it's own.. and scale the RAM frequency down also..

Tried 400FSB, still no workies :/

If I know the maximum voltage limit for this Sempron 190, then I'm happy to run it at that all day.

Can't find any websites which tells me the Sempron X2 190's Voltage + Thermal specs, not even CPU-World, nothing on AMD's website either, only thing I can follow atm is the Athlon II X2 260 which is Regor, same as the Sempron 190.

The Athlon 260 is a 65W though, whilst the Semp 190 is 45W, so it can't be that right, the Athlon 260 has a thermal limit of 74C and max voltage of 1.4V coming from CPU-World.

EDIT: Just E-Mailed AMD regarding this information.... Gave them a screenshot of it running at 3.76GHz also,
no doubt they will ask me about my CPU's serial number etc so they can reject any future RMA's lol

You may need better ram to hit a FSB higher than 300. I had some G.Skill Ego 1600 that wouldn't go pass FSB 275 than I tried A-Data 2000 then I hit 350 FSB and stable on a 890FX mobo.

Max voltage for 45nm AMD chips is 1.5-1.55v and temps below 65c but ideally below 55c for stability.

Yes, it's made on the same process as the Athlon 2 and Phenom 2's..... The Sempron doesn't use a weaker process with weaker transistors thumb.gif

Great, I'll be back with screenshots of the BIOS if I can't get it to boot at 4.0GHz again thumb.gif

Yes, it is made from the same silicon so the same restriction apply.

Personally I think you worry too much about damaging your CPU. The CPU will not die because you run it for a few hours at 1.55V+ and moderate temperatures running some benchmarks. At worst the CPU will degrade slightly.

As for you not being able to push the CPU past 300 HT ref clock. Please re-read most last post the other thread you created earlier this week regarding the CPU/NB being the key. It could be that with you CPU/mobo/RAM combination frequencies above 300 are simply not possible. Then you should try different RAM and if that does not help a different mobo.

Turn the CPU-NB down to stock, keep the both it and the HT as close to stock as possible.

Set RAM to 9-9-9-24-2T @ 1.65v

I have no idea why you have messed around with all the sub settings, there's no need on such a small FSB clock, put all the sub settings back on stock.
