MSI Neo2 Platnum - strange overclocking results..

[Alphafox78]

hey all
very strang stuff...
just got a 3200+ winchester .90 CPU, its nice. also have 2x twinx corsair 3200 non LL ram.

overclocking idea: I had in mind that since my ram doesnt OC very well (220 max) I was going to get the neo2 and play with the FSB and set the ratio of the ram to 166 or something so that I could up the FSB which would in turn up the ram to around 200 or a bit over. thats the idea anyways...

result: initially I could not even post with this ram, had to flash to 1.3 but now it works. when I try to set the ram to 166 and start upping the fsb, I can get to around 220 fine. any more than 225 and I cant post... huh??? the ram is only running at 183 or so mhz at this point so I know its not that. I raised the voltage of both the cpu and ram to 10% and 2.80v and still had same problem...

ok, so I thought I would just change the fsb to 133... well again around 225 or so I cant post... ram is running at 150 only then, so definately not ram. I am lowering the HT to 4x and 3x and still no difference..

my last resort was 100mhz.... well oddly enough, when I set the ram to 100 I can up the FSB to 270 and it posts! I can boot windows at 260 fine, cpu is 2600 and ram is 133 at that point... well the ram doesnt bench too good there obviously, like 3100 in sandra.

the only other thing I could thing of was upping the FSB as high as I could go to get the ram up there and lower the cpu multi while leaving the ram at 100... I was able to get it up to 300 which the ram runs at 150 and booted into windows. but zcup said that HT was running at 300mhz... when I tried to up it from 3x to 4x it posted all weird, so I dont really want to stay at that level...

anyone else had issues changing the ratio?? I tried 1.37 with the same result.

facts: in 1:1 I can run up to 220 and boot windows, so ram runs fine at 220 and cpu 2.2ghz
: the CPU runs fine at 2.6ghz so the cpu is ok

the only conclusion I can come to is that the motherboard is wacked out.. I think the bios is crummy or something. I cant afford new ram; I only wish I could change the multi on the CPU!!

any thought are appreciated

What is it with anti-MSI gang bang crew spreading this review like it's the plague and not knowing the full story? I'm not a MSI Neo2 owner btw, but have used 3 for custom builds, and it overclocks like a charm using whole integer multipliers as many enthusiasts will recommend (at least until bios fixes prob). This was known way back in early Sept the A64 Nvidia 250 3 ultra's cannot do half multi. Even our very own Wesley here at Anand confirmed such. It's no big deal.

im not using 1/2 multis. where is my post did you get that idea?? its the ratio im having problems with

having the same EXACT problem. Happening at the same EXACT clocks. It's very frustrating. I'm starting to wonder if 133/166 for the "Max memory clock" is breaking the pci locks. I'm running a 3000+ Winchester with 2x512 of Hyper X PC3500 (CH-5).

It seems like it's just a problem getting it to boot. When I boot it up at standard clocks and use clockgen to raise the FSB I can hit over 270 at 5:4 (or whatever 166 corresponds to).

Have you set AGP clock to 67MHz, and are you using SATA ports 1 and 2?

 

[Alphafox78]

well for me it turned out to be my corsiar ram. I put some generic stuff in there and it works fine past 225 with the ratio at 133 or 166. for some reason at 225 it still does it, but once I go past that it works. Im going to RMA the ram. implicit1, try different ram if you can.

AGP is 66 and using 3/4

 

[implicit1]

I'm using AGP of 67 on SATA port 3.

Alphafox: I believe that your Corsair uses the same chips that my HyperX uses (CH-5), so it must be some compatibility problem.

The strange thing is that I'm priming (at 12 hours so far) at 277FSB with the 166fsb divider. It just won't boot at these speeds. If I use A64 Tweaker to set the ratio, and clockgen for the FSB it works fine. I guess this will be a good temp solution until I can afford some new RAM.
