Hello everyone,

I'm having a small problem while OC-ing my PC.

The parts are:
AM2 x2 3600+ Windsor (200x10, 1.25V)
Gigabyte M55Plus-S3G (Rev1.0 with Nv 6100 IGP and 430 SB)
Using the IGP, no external GPU
Fortron 400W PNF model
Hitachi SATA2 HDD

The "problem" is that I can't boot while having the HTT set in BIOS over 280Mhz. Firstly, let me ask if someone has the board ? Can that someone boot over 280Mhz without problems ?

Next thing, I din't write what memory I have, cause I tried many of them, 2x512MB Crucial Ballistix (which went to 1150Mhz CAS4)
2x512 GoodRAM 667 Value (go to ~830Mhz CAS 5)
2x1GB Crucial Value 667 (go to 860Mhz CAS 5)
2x1GB Apacer 800 (~880 CAS5)
1x512MB Corsair (~900 CAS5)
2x1GB SuperTalent (~1050 CAS5)

And the board works great with the Crucial's, GoodRAM and SuperTalent with which it went to 270Mhz HTT without any problem, rock stable. Apacer and Corsair didn't go so good, bootable at 260Mhz, and not 270Mhz.

I tried all the memory dividers with all the memories (of course, some of them push the HTT on 1:2 divider cause of their limits), tried lowering the HT multy, tried putting in a PCI graphics card, raising the PCI-E frequnency (you never know ) raising Vcore and chipset voltage, lowering CPU multy...I'm not a n00b but this is killing me (softly :p)....

Tried with clockgen in windows and it showed that the board could easily go over 300Mhz in Windows, stable of course (think I got to ~330Mhz without any problems) - so the conclusion is that something is stopping me.

What could it be, has anyone got an idea or a solution ? The BIOS, memory compatibility (), memory dividers not working so good, what ?

The PSU is not a problem, it's one of Fortron's finest , and it pushed a stronger PC without a problem (OC-ed E6600, 2GB, X1900XT and much more).

I, like don't have any more ideas. Does anyone have a solution ? A BIOS option that I didn't try to change ? Or is it simply the board and/or the BIOS ? Maybe the CPU that doesn't like some dividers ? It is a budget motherboard (chipset), but as I can see on the net, many Gigabyte boards are having a hard time booting over particulary frequency's...

Thanks in advance and sorry for a long post
