Ultra LSP650 on Sandy Bridge Build Issues

post #1 of 4
Thread Starter 
The details are largely in my sig. I had my Sandy Bridge build up to 5.3 GHz for 4-5 days and 4.8GHz for about a week all stable under Prime 95 Blend stress test. Everything was fine until the CoolerMaster Hyper N520 I had quit cooling as well as it was and idle temps were 30C instead of 20C Overclocked like before, stress temps were 70-75C as opposed to 65C before while Overclocked. So I went out and got a Corsair H50 ( which I shouldn't have returned now no RMA'ing the entire thing through them ) and Spend some time making sure it was mounted right booted it up and the idle temps were 40C with stock bios settings!

What's worse is even after I double checked that it was mated properly it cooled down some 35C I was like ok maybe that normal maybe it idles at higher temp and tops at lower. So I stress tested it and it got to 80-85C my failsafe's started kicking in by the time it hit 80C so I removed and returned the H50 without trying to see if it would boot with stock cooler. I went to the store and got a CoolerMaster V6 GT got it installed which took awhile instructions were smeared. Anyways I got it installed and all the lights came on, all the fans started up, DVD and HDD's power on, but it still doesn't post.

So long winded story out of the way I did the following.
So I tried moving the CLRTC jumper, unplugging PSU draining the power by pressing the power button 10 times ( holding it for 15 seconds on the 10th time ), removing the CMOS battery, re-seating the RAM, re-connecting the HDD's, unplugging the Cooler replacing with stock, switching GFX card slots, unplugging GFX card, using backup GFX card ( which is powered by the lane and didn't need PSU connection ), I tried adding another 300W PSU in addition to my 650W,Disconnecting all case fans, running a MemOK! onboard RAM test. Tried using the crash-free bios feature with both a thumbdrive with latest bios and the motherboard disc which also failed.

I was using BIOS 1305 which is not on ASUS's site anymore. Soem people in the other sub-forums think it's a PSU issue,so I wanted to ask here. Does anyone here think it's a PSU issue? I haven't dealt with Ultra's RMA yet but hear it's a nightmare?

Anyone?

OK nevermind I just put it in a friends old AMD rig. The -5v and PCIE connections are toast.

Modern PSUs do not have -5v. It is the "missing" wire in the 24-pin harness.

PCIe not putting out power is of more concern.

If you suspect the PSU, the first thing to try would be a different PSU. Hopefully one better than the LSP650 anyways, since that isn't a great unit to begin with.

Yeah the tech guy mentioned that about the -5v last night, after fiddling with the tester some more I think it's showing the PCIE as being powered either way Ultra is sending a new one and i have an XFX 750W Black on the way and will use the 650 as a backup unit. I tried another PSU in addition to the LSP650 didn't help main problem is I don't have many "modern" PSU's I have one in my AM3 AMD rig ( though it does have a -5v )
