  1. Hi guys, I'm in the process of speccing up a new rig, and I've hit a bit of a bump when it comes to RAM, specifically whether I should go for a cheaper DDR2 based rig, or whether I should go for a more expensive DDR3 based rig. Now, this rig will be mainly used for gaming with some DB development work done as well (until I can build my own test server), so speed is key, which suggests DDR3, however, everything I've seen up to this point says there's next to nothing between current DDR2 and DDR3 modules. Another thing to consider is that I'm hoping that this rig will last me a few years, so I'm looking to future proof it somewhat, and it seems to me that DDR2 is coming to the end of it's design/development lifecycle, whereas DDR3 is just starting. So, my main question is, for a system that I hope will last a fair while, should I go down the DDR3 route, or build a DDR2-based system? Or, alternatively, should I wait until DDR4 comes out (which has been rumoured to be around Q3/Q4 this year). Thanks, Thanks,
  2. Hi Sharp, I've replaced the old CPU and everything works fine (I'm just waiting for all my standard stability tests to finish, but it all seems good to go at this point) so you were right and that it was the CPU. This has taught me 2 things - keep track of what you send back, and don't bother getting OEM version of key bits of kit. For reference, my CPU part number is Y971404I60260. Cheers for the assist on this one lads, you've both been really helpful.
  3. 3Stars - Both memory modules have passed a 3 hour BIOS MemTest, 2 'enhanced' Windows Memory Diagnostic Tool tests and an 8 hour Prime 95 RAM heavy torture test, so they appear to be working fine. Sharp - It's an new OEM CPU from Overclockers.co.uk. I probably should admit, though, this one was an RMA replacement after the first one turned up bent. The IHS is still on, and intact and as far as I know, it's never been dropped, bent or slightly damaged, but that doesn't mean it hasn't in it's lifetime (7 years is a long time). Thanks for those - I followed your instructions to the letter, but it refused to boot. I even tried swapping the modules over, but still it had no effect. I've even tried your settings with different voltages, including 2.71v, 2.72, 2.74, 2.77 and 2.79v. I'm hesitant to push it above that since the RAM says it's rated between 2.6 and 2.8. Since the RAM seems ok, whats the chance that this is a motherboard issue?
  4. Hi guys, I've recently decided to upgrade my lowly 3700 single core rig and go for a 3800 x2 processor to tide me over for a little bit longer until I can rebuild my machine properly. Unfortunately, in the process of upgrading, something seems to have gone wrong. Now that I've dropped the X2 core in, whenever I try to boot my machine with the RAM in Dual Channel mode (taking up both the orange slots on the board), it boots to 3 LEDs and stops. Typically, this means that there's an issue with the memory, but I can boot the machine fine with either module in DIMM 2 (the orange module furthest away from the cpu). I've managed to boot the machine with the RAM in both DIMM 1 and DIMM 2 slots (working, but not stable), but never when there's a module in either the DIMM 3 or DIMM4 slots. Has anyone here had the same/similar problem as I'm having at the moment? I've searched the forums using various terms, but my search-fu may be weak. I've reset the CMOS quite a few times during my testing (but never more than 3 hours). Should I try a full 24 hour CMOS clear? (I'd have thought that leaving it clearing for 3 hours would do the trick but hey) With regard to the motherboard settings, all I've done up to this point is set it to optimised defaults, which seems to work when it's running on 1 DIMM. I've tried putting both modules in the orange RAM slots and running with CPDMF's settings his set up is identical to what I've got, but it failed to boot past 3 red lights. I saw a post on here with the recommended defaults for that processor, but not my RAM. Does anyone have any stock settings for a 3800 x2 on an Expert board with G-Skill 2x1gb PC4000 RAM? And does anyone have any idea's or suggestions as to what might be wrong?
  5. Hi guys, Just thought I'd post a quick update on this problem. Basically, we must've had a power surge that fried my PSU something rather nasty as it refused to work with any motherboard I plugged it into, and so the PSU has been RMA'd back to Antec. In the mean time, I went out and bought a Seasonic M12 550w PSU, and I've got to say the difference in noise is astonishing! My machine wasn't overly noisy before, but now I can barely hear it, even if I try to listen for it. Thanks to all for your help on this - it's been greatly appreciated. PC Juice - are you sure the PSU you're using is powerful enough to cope with the amount of power your rig is drawing from it? Ray Wise - this was happening to me before the PSU went, so it might be an idea to watch out for. It might not be the same issue, but forewarned is forearmed as the saying goes.
  6. Hi all, I've had my PC set up and running fine for nearly a year, but I went to turn it on on Saturday morning to check my email, and I got absolutely no response whatsoever. Checked the power cable, plugged in fine, PSU is on and everything looks like it has done for the last 6 months, only nothing happens. For reference the rig is based on a DFI NF4 SLI-DR Expert board, with an AMD 3700+ CPU and GSkill DDR400 RAM (2 x 1gb). VGA is an Nvidia 7900 GT and the PSU is an Antec TruePower 550, all of which is set up to stock levels. I've not changed/altered/tampered with them at all. When I press the power button on the main box, the machine flicks on for less than a second, I see all 4 Diag LED's flash, the DRAM light flash, the fans twitch, then it all stops. The Standby LED on the motherboard is always lit. I've been over the suggestions on this board a few times, but they all say the same, roughly. Clear CMOS and report back. I've done a 30 second, 1 minute, 3 minute, 15 minute, 1 hour, 8 hour and now 24 hour clear, and one thing has become clear. Every time I do this, I get to the step that says 'Start the machine' press the power button and nothing happens. No diag LED's, no dram LED, no motion from the fans, nothing. I have to wait a few minutes before it goes back to what it was doing before, which is of little help. I've searched and although I can find a lot of cases similar to this, I can't find on that has shown the problem of waiting until you can try to power on the motherboard. From speaking with friends, they've all suggested it could be the PSU (which is highly likely), but one or two has said it could be the motherboard. Has this happened to anyone else, or can anyone else shed some light onto this at all?
