I have an XP 2800+ Barton core. Runs around 39-40C on Air cooling with an SLK-800 and a Panny fan. Right now it's running stock. I was thinking of picking up some DDR3200 memory and running it at full bus (12.5x200) instead of (12.5x166). 2.5ghz vs 2.08ghz Has anybody done this yet? Think it will be stable with a 400 mhz increase?
 
Depending on your mobo and the type of RAM you buy, sure, it should work great. I've got a friend whose system I set up and OC'ed and he's running a 2500+ at 11x214 for 2.3Ghz with Corsair XMS 3200 (I think it's the C2 variety) on an NF7-S 2.0. You should be able to do better than a 200Mhz overclock, if you wanted to. Have to watch your heat though...
 
im running my 2800 barton at 2.4 13multx185fsb in a really hot room (about 35c+ ambient temp atm heh) the proc is sitting at just about 50c under a full load. Once I get some AC in this room and get the air temp down a bit ima push the fsb up more and back off the multi a bit as I dont have a good HS on the northbridge (soltek mobo)
 
I have a 2800+ as well on a a7v333, I only got 2700 ram though.... how far do you think I can push it? it's at 2.25ghz right now....

I have a SLK-900 with panaflo L1

THat's pretty much what I have...except the mobo is a MSI k7n2-delta (nforce2-ultra). My temps are pretty low...so i'm thinking I can get some PC3200 and just run it at 400mhz bus. Just wondering if the chip can handle it.
 
I don't think my mobo can take 400mhz fsb. I checked the site and it said it only took up to 3000+ so I'm guessing the mobo only goes up to 333 fsb. Or else I would have bought the 3200+ instead.
 
Their is no way that your barton 2800+ will reach 2.5ghz that is simply not going to happen. I have had 2 2800+'s and 2 2500+'s and none would go past 2.35ghz with up to 1.9Vcore. It took my 5th chip a barton 2500+ mobile to reach to and past 2.5ghz. However I would expect you to get at least 2.2ghz out of it with 1.75Vcore.

For ram I would run pc3500, get some low latency stuff and go for 220fsb if you give it some juice. However, the abit has problems with high fsbs as anyone will tell you which is unforuntate and thus this is why everyone is moving to the dfi since you can get good high fsbs, without having to modd Vdimm and northbirdge voltage which you would have to do one the abit if you want to get much over 220 or for some boards even get to that.
 
My 2800 will go 12.5 x 200fsb at 2500 mhz @ 1.75 v. It would pass prime95 and PCmark, but not either of the 3dmark tests

I Cannot change the clock multiplier, is this cpu locked!!??? HELP

I have tried everything between 13.5 - 11.0. All at 166mhz. Nothing worked. Tried 185 at 12.0 mutiplier like guy above didnt work. Why wont my CPU let me change the multiplier? Is it locked?

Thanks for any help.
 
I need to get together with someon local to austin. I just got my 2800+ together running at 1.78ghz with nothing done to it. NNow i have my 1.3ghz thunderbird that i want to try my first OC on. I have no idea where to begin guys. I see the 2800+ oc'ed to 2.2 and i'm like WOW. I will read annd learn. keep pushin the limits guys!
 
I have an NF7-S 2.0 with the Barton 2800+ with 2x512mg 2700 ddr running at 2.25 (13.5 x166) at about 54C is that too hot ?

seems to run fine, no glitches yet

It's hot for my taste, but as long as you're talking load temps then that should be within a safe temperature range. Is that a typical load temp or a typical idle temp?

That was an semi-idle temp nothing too strainuous, but also considering it was about 95 F in my room that day the AC was out :( just new to o'clocking this cpu/mobo combo and did it by accident kinda wondering if it was safe...
 
I read somewhere online 85C my mobo shuts the system off at 75C which happened one time when I was installing something and a wire got caught up in the cpu fan and it didn't start, my pc shut off with a wicked alarm right after bootup
