max HTT 6150/NF430 can handle?

[gedon]

I'm using an ASUS A8N-VM-CSM together with a new Opteron 165 since february. The VM-CSM is more a business board only a few overclocking options. The Opteron can run at 2.6Ghz with 1.37V. I increased voltage to 1.41V via Christal CPUID and was able to clock this thing to 2.65GHz (295x9). At wednesday I found a working pinmod at www.ocinside.de.
yeah 1.55V, but it doesn't want to run faster.
I think it's the board or the chipset. I tried to lower both multipliers (CPU to GF6150 & GF6150 to NF430) with no luck, memory-multiplier down to 100/200.
I use a 6600GT instead of the onboard graphic.
I put these 3 things, 6 hdds and 1 DVD drive into an aspire x-qpack and there is still one 5 1/4" bay free . I love this small case.
But I hate this board. It don't go any higher. Before I buy a new µatx board from MSI/Foxconn,... I wanna know, if the chipset is limiting me. If it is, I will leave the µatx way and go with a normal NF4 board in a normal midi tower.

Bump.

i dont know about the 165 but the 148 loves the dfi and asrock mobos
at stock voltages.

I'm 99.9% sure that it's not the CPU. 2.6GHz at stock volts, but it's unstable at 2.7GHz with 0.2V more.
It's more a board or chipset limitation. In all reviews about GF6150/NF430 boards I found they overclocked their boards only via bios.
max htt bios: ASUS 240MHz, MSI 250Mhz, Foxconn 300MHz
Why did they forget ClockGen? I think I need something like 320MHz htt.

okay...I don't think 6150/430 are made for high ocing.
I ordered a DFI nf4 Ultra D. My ATX case needs some modifications. I hope, I can finish it at the weekend.

Keep us posted on your progress...

hmm... okay, the first x16 pcie slot of the nf4 ultra d in single-vga-mode has 16x bandwidth. the second x16 slot has 2x bandwidth.
Can I put a pcie x1 card into the second pcie x16 slot?

[wolverineI]

you can run a pcie card in either slot. i had to, to get mine running as the card had a bad connection on it,only worked in the second slot till i cleaned it.but what is a pciex1 card.you can also mod the ultra d to run sli using both slots.

Hi I have this chipset also and am having problems overclocking I think its my PSU so getting a new one.
Whats all this spread spectrum stuff ?
CPU spread spectrum, SATA and PCIE settings are disabled center or down ?

@wolverineI
problem solved, I put a cheap pcie x1 raidcontroller into the second pcie x16. that works great.
the NF4 Ultra D has one pcie x1 slot. it's located between both x16 sots. it's shorter and slower than a x16. pcie is downward compatible, that means you can put a x1 card into a x1/x2/x4/x8 or x16 slot or a x4 card into a x4/x8 or x16 slot

@grandmaster_b
what board are you talking about? ASUS A8N VM CSM or DFI NF4 Ultra D?
what PSU, CPU and videocard do you have?

[grandmaster_b]

I have the M2NPV-VM which has the same chipset as the A8N-VM-CSM I think.
I have a Enermax 535W PSU on order, I am using the integrated 6150 GPU.
AMD AM2 64 3800+ Orleans Core.
Kingston Hyper 900Mhz rated memory.
IT says the board only supports 800mhz mem max so I assume that I could overclock the memory to 900mhz or if that fails then underclock the memory to 800mhz.
Thanks.

[gedon]

socket AM2, that means DDR2. I have no experiences with DDR2, but first I would set a memorydivider and underclock the memory. this way it can't limitate cpu overclocking.
I wasn't able to clock my memory higher than 205Mhz, now with the DFI board 295MHz.
never used the onboard graphic, maybe it doesn't like more than 200MHz htt clocks.
btw, leave the spreadspectrum setting at it's default. I needed 10min to turn the pc on: power on, wait some sec, power off, wait some sec, power on,...

Hi guys I am having memory problems with this board I was ambitous and bought Kingston 900mhz rated hiper ddr2 I cant get it to run stable on anything other than 400mhz !
I can overclock the board to 225 but if I have to keep the memory to 400mhz is that a limit of the board ?

What timings have you set the memory for ? Kingston can be very awkward with its SPD, I never bought any of it for that exact reason.
