ABIT NF7-S stability above 200

I am having stability issues at speeds above 200 on my motherboard... I truly think it goes back to this board... how cool is ABIT about RMAing... if I sell this board off to someone, what board should I go with for an upgrade if I am using a Mobile Barton 2500+ and Corsair PC3200 Ram... AN7? I will still need a RAID0 setup.

I can't exactly say, "Hey, ABIT, your NF7-S is giving me trouble running a CPU way above its specifications. Give me another board so I can see if its chipset can handle these high speeds."

My other computer with an NF7-S is running rock solid at 210 with much cheaper components.

I've heard that sometimes the chipset needs better than stock cooling for overclocking, you could try putting a fan over the northbridge.

I got a crystal orb for that when I added a SP-97 on my cpu... but the crystal orb did not quite fit, so I ended up with some AS5 on the stock heatsink/fan... man, having my board out and finding out the orb did not fit pi55ed me off... but looking through my case at the fan on that thing right now with a flashlight, it looks like it is missing a beat... in the spring, it was making some noise, but the noise went away :smile: so too could have the effectivness of the fan... someone just tell me what to buy for that chipset and where to buy it from... that would be awesome... I ordered a Zalmon something over the summer, but I ended up putting/sticking that on the SoundStorm chip... besides, it was passive...

I really don't know what to say, I usually make my own when faced with these types of problems.

I will find something... newegg did not have what I wanted a few months back, and I would order from them in a heartbeat, bestbyte, too, but exploring beyond those two places takes more effort and trust on my part...

Because it pushes into the motherboard, I want something with push pins that fit it perfectly...

The big deal if getting it and then finding the time to take my motherboard out and do the job...

Your lack of FSB could also be a chip problem. I can push my NF7-S to Hyper-X PC3500 limits, but this unlocked XP-2500 is unstable above 2.16ghz no matter where I set the multiple or the buss speed. If I keep it down at 10.5 X 206 it's fine. You may have reached the limit of that Mobile CPU.

Here is the weird thing... I had a 2600+ on this motherboard, and 208 was as high as I could go prime95 stable with a very high VCore... I moved that cpu to my other NF7-S computer, and I got it at 210 with a much lower VCore... and did not try going avove 210 because I am using PC3200 value ram and did not want to bother testing higher limits...

I posted this info here over the summer. I will a quick search and post this weird problem...

OK, here is my old post...

*********************************************

I had a Mobile Barton 2600 in an NF7-S v 2.0 that I thought was a lemon... I maxed out being Prime95 stable at 208x11.5 at 1.82+ VCore... I have 2 XMS Corsair 3200 512MB sticks of ram running dual channel at a relaxed 3449 and 2.8 V... and my cpu is cooled by first a SLK900A and now a SP-97...

My 2nd computer has an NF7-S as well, bought at the same time, and I had a regulat Barton 2500 in there at 11.5x200 @ 1.76 VCore... I sold this Barton at a good price and bought a Mobile Barton 2500... I moved the new cpu into my 1st computer and the lemon 2600 into my 2nd rig...

When I put the 2600 into my second computer, thinking I know the CPU's limitations, I set it right away at 205x11.5 and run Prime95... [I leave the bus at 205 because I have not tested how far the Corsair value ram pc3200 can go] it runs for a few hours and does not crash... then I realize my I forgot to adjust my VCore... it is still at 1.76 [1.8 in the bios]... I bump the bus up to 210 and it still does not crash while running for about two hours... this is at 210x11.5... on my other computer, this cpu was never stable at a 210 bus... 208 was really as high as I got Prime95 stable... and that was at 1.82 to 1.84 VCore, not 1.76... and I have not lowered the VCore to see if it is still stable or raised the bus to see if it goes higher than 210...

I want my 1st computer to be my best computer; it has the RAID0 for video editing, the 9800 Pro, the full GB of XMS ram, the larger, newer hardware... this just pisses me off...

The new mobile 2500 did do betterm in my 1st computer, but I still leveled off at 210x11.5 with a VCore at 1.82 to 1.84... my power is an Antec true blue 480... my heatsink is a SP-97 with a 80mm SmartfanII running about 4800rpm... my temps have been great today...

Any ideas here... is my ABIT motherboard the lemon here... I hate the idea of having to swap motherboards... jobs like that are so hard with a new baby around and a wife that gets on me when ever I take the side of a computer off... she was out of town today...

Hehe, I'd cut down a Slot-1 cooler so it was just the center portion with 2 tabs.

Well, a 230 Buss speed is about tops on this board. I don't know anybody running faster. I also don't know anybody that can't hit 220 speed either. Cooling might make the difference, but the jump from 210 to 220 is nada. I'm running 120mm fans and a CoolMax with a 120mm fan in a XoXide case. It has an 80mm side fan (intake) and a 92mm Thermaltake blowing down on the Zalman 6000 AlCu heatsink. My CPU has hit a high of 58C @ 1.75v. This puppy moves a lot of air. I guess I would swap for some PC3500 memory with a buddy and see what happens first. 210mhz to these boards is nothing.

Here's a link to an outfit selling a NB cooler and HS for the mosfets. I was interested in it for my NF7-S but haven't yet got around to it.

Otherwise peeps are using the Vantec Iceberg for the NB

I might try the Vantec Iceberg... how important are the mosfets?

I ordered a copper Vantec Iceberg last night, and I am glad I did... when I booted up just now, I looked through my case with a flashligh, and my fan has stopped turning... I just dropped my bus to 180, and I guess I have passive stock cooling until I get the Vantec Iceberg on there.
