Anvilator

I've got a stable clock with my current settings, but when I play around my system often this error. From my experience, it seems it can have as much to do with RAM settings as CPU speed. Try looser timings as well as the other things mentioned here. One things for sure, if it's happening, your system aint stable. Don't be scared to try higher voltages with your gear, it can often be a quick fix to unstability. I've got most of my voltages up at least a bit, and have never had problems. Just keep an eye on temps to start with.

Ok, thats what i thought might be the case. I was hoping that the slots might change when a gc is detected only in the second slot, so the first one would be 2x and the second one, when in use, would swap to x16. I guess I can scrap that idea, or change the jumpers and go for x8. Cheers

Hi all, I don't know it this has been talked about before, but I want to know if anyone can provide a definate answer to this question. If I use the second pci-e 16x slot for my single graphics card, will it still run at 16x? I have tried this, and it seemed to, but it was a bit hard to verify. I am asking because with my over clock (3200+ venice at 2.5Ghz) the chipset runs hot. It can get up 55-60 degree celcius. Is this ok? I want to run my gc (leadtek 7800 GTX TDH extreme with the same heat sink as the 7800 GTX 512, huge!) in the second slot, so i can put a better heaksink on the south bridge chipset. (swifttek MCX159 http://www.pccasegear.com.au/prod2833.htm). I feel this will provide better stability when i finally get round to shooting my oc to 2.7 or 2.8 Ghz. Anyway, does anyone run their graphics card in their second slot, and does it run at full pic-e bus speed? Cheers, Michael

Hmm, looks like it would fit on the Expert. Oh well.

Gday all. At the moment my chipset constantly sits around the 45-50 degree celcius mark, and the fan is rather noisy. I understand this is not particularly bad, but I'm trying to push my system as far as it will go, while trying to also make it quieter is possible. If I'm not mistaken the chipset cooler is the low profile fan next to the top pcix-16 slot? My question is concerning the Swiftech MCX159-CU.(http://www.pccasegear.com.au/prod2833.htm) (http://www.swiftnets.com/products/mcx159-CU.asp) For a start, will this fit on the board (SLI-DR), or is it just going to get in the way of the graphics card? Secondly, can you rig the mobo to run a gc from the lower pcix slot at 16x? And lastly, is there a big benefit to running with a cooler chipset? I have read else where this can have a large effect on the overclockability of the system, with results increasing by up to 300Mhz on some systems. In any case I have written this hsf off, as it appears there is no way it will be possible to attach it to a nF4 SLI-DR with a full size graphics card. I already have over lap problems with a medium size gc and the oem fan. Does anyone have any other suggestions about dealing with cooling the chipset, and is it worthwhile. I'm looking for at least a 10-15 degree decrease. Cheers

Gday I recently overclocked my rig, and it is doing something sort of similar, but probably it's different. It seems, after reading through a few threads, that people might be buying the vxpc4000, but not pushing it enough. Anyway, I have OCZ ELPC4000VX, and I have pushed it to 500Mhz at 2-2-2-8. It runs in a totally stable state when put at 3.3v or 3.4v. at 3.2v prime95 bailed at 45mins, but at 3.3v it ran fine for 10hrs44mins, until I stopped it. The thing is it will not cold boot. It warm boots fine, and takes anything i through at it and runs with it. If i turn it off for a few hours though and then try to turn it on it gets to the thrid LED (ram check) and reboots. I've over come this by clearing the BIOS, and it will boot fine then. after having it on for 5 mins, to warm up, if i reboot to the BIOS and overclock it, then save and reboot it will boot fine. If i run this machine at stock settings there is no problems at all, fullstop. it will boot fine, run stably. First I thought maybe the ram doesn't like 3.3v having slammed into it when it is cold, so i turned it down 0.1v, but then the computer wouldn't boot at those settings. I have put it up to 3.4v to see if that fix's. maybe it needs more voltage for a cold boot? In any case, has anyone had this exact problem, and knows what causes it, and how to stop it happening?
