As I can`t use my PC at the moment, as I am swapping the 2500k for a 3770k, I thought I would put together a temporary system.
So using a GB P35-DQ6, a Q6600 GO and 2x2 OCZ DDR and a 612S cooler. Got it all built up, using the Psu in my sig and then I hit a snag. The fan on the cooler quickly spins up(then stops), the rear chassis fan just about turns(led light is just a flicker). The Psu fan turns over, then stops, if I leave it, it is just an endless cycle. Changed the ram for 2 other sticks, even tried with just 1 stick, same thing. So, I have power for about 10 seconds. Tried another 500W no name Psu, this only had a 4 pin Cpu power connecter, the board needs an pin, but I get the same result as before.
I have nothing else connected, no Gpu, hdd or optical drive. I have removed the Cmos battery, but I doubt that will help in any way.
Now my Psu was working this morning prior to me taking out the Cpu. And tbh, I have rarely heard the fan spin, certainly not as loud as it is now.
I`m going to take it all out later tonight, although I don`t think it is shorting.
I will check the pins behind the Cpu, to make sure there are no bent or damaged pins. The Cpu came installed when I bought it on the MM, 18 months later I finally get round to building it.

if the board has an 8 pin cpu socket you can use half of it with the 4 pin plug on psu

done a cmos/battery out for 30 minutes?

Already tried it with the 4 pin on the cheap Psu, but I get the same results. That is way I am wondering, if it might not be the Psu.

Cmos battery has only been out about 10 minutes.

if the cpu cooler/heatsink has a backplate could try loosening it off a little

Just tried outside the case. No cooler, 2x2GB ram and a 9500GT, Stlll exactly the same.
Just can`t understand, how 2 Psus known to be working, can`t power up continuously when connected to this motherboard.
 
Chip arrived this morning and Psu is OK( says I, with a sigh of relief). So that means a problem with the mobo.

try clearing the cmos again then add in the two sticks of ram

EDIT: I see you've got it working,does it show dual channel in cpu-z though?

Tried the sticks in slots 1&2. Got into the bios and shows 8GB. Went into windows, opened up CpuZ and it all so shows 8GB in slots 1&2.

@ hono, have had the latest bios for ages and the board came with 3 bent pins.:D But they are only associated with onboard graphics, which the Sabretooth does`nt have.
 
wazza300 said:
so it shows running in dual channel in cpu-z? single channel is no good(if its saying single)

ohh and arnt you tempted to straighten those pins?:eek:

Dam, showing as single. I can`t understand why they wont work in dual channel mode with the new chip. I`m at a loss.

In regards to the bent pins, they are as straight as I can get them and are not making any contact with any of the other pins. And as I said earlier, they are only for the onboard graphics. Besides the mobo has run perfectly for nearly 2 years.
 
wazza300 said:
aslong as your sure they are for onboard,don't forget the 3770k is different to the 2500k

hyperthreading ect

bent pins usually = memory issues,same as overtightened cpu cooler/flexing motherboard

done a cmos clear yet? it could be messed up slightly from your old cpu being in there

dual channel and two sticks is always slots 2 and 4

0 1 0 1

1 being ram stick installed 0 being empty

Going to try removing the Cmos battery and see if that helps.
The ram has always been in slots 2&4.
Before I bought the mobo, I got the pin layouts for the board( from Asus forum moderator) and the chip( from Intel). Using the two together all 3 pins were associated with the onboard graphics. I also checked it 3 times to make sure before buying it and the results were the same. And I have never had a problem with it.

try re seating cpu a few times aswell,maybe its disturbed something

Just realised that to remove the battery I have to take the thermal shield off. Now I do have a clear RTC RAM jumper switch, so would this work, saves having to virtually strip the system out.

yeah if you leave it on a for a while 10-15minutes,hold in front panel power switch to discharge the board of power

Update.

Took the chip out to find it had bent a few pins, so took it to this guy I know, who managed to straight them out as best he could. He reseated the chip and I took it home. But I thought I would check it was OK before building the system up again. But for some reason it had flattened a couple of the pins he had already sorted. Any way, did a bit of jiggling and got it all up and running. But as soon as I upped the ram frequency, I kept getting blue screens and ram voltages of 1.66500v. This was using Win 7 on my ssd.
Tried an installation of Win 8 on a hdd and all up and running. Now I have to see if I can run the ram at 1600 and at 1.65000v.
Temps as I write this are just under 30c@idle.
 
I seem to have everything back to normal now. Will take some screen shots of my bios settings and post them in the other thread tomorrow, in 8packs section.
And thanks for the help and advice so far wassa, really appreciate it.

ahh im glad you got things sorted out

you went through a bit of hassle but got there in the end,looking forward to seeing some overclocks;)

I have it running stable at 4.5Ghz and temps just under 70c. Will run Prime95 when I go to bed and monitor temps and voltages. What`s the best setting to run on Prime95? Ram voltages seem a bit high but will also try lowing them when tomorrow as well.
 
wazza300 said:
well I don't use prime95 tbh,but a blend test will test cpu and memory

I just do 5 runs in ibt then lots and lots of gaming,you'll see that ivy is a bit different to sandy when finding stability

ivy will fall down almost instantly in gaming and yet can be ibt and prime95 stable,games will crash to desktop if your too low still on cpu voltage

don't have that happen with sandy,it will just fail the stress test or crash in something besides games

Just had 2 hours on Crysis 3 without any problems, so must be stable. :D

Oh so I was right about the pins then? ;) Where's the love? :'(

Give OCCT a bash dude in Linpack mode. I personally prefer it to Prime. You can monitor temps and voltages, easily set a time period and it generates handy graphs for you to review once the test is complete.

Really glad you are on track now bud :)

Tried both OCCT and IntelBurntest, temps were in the 80s.:eek:

I will be playing around with it tomorrow. Got a couple of fans to put in the front and a fan controller to install. Then I can get the side panels back on and see how much cooler it will be.

that's alright

my 2600k needs more for 4.5ghz

but less is always better if you can get it

That is the part I can`t get my head round. If I lower the voltage, how do I stop it from increasing again when stress testing. What other settings do I need to adjust?
