~~ New 1800 - JIUHB DLT3C ~~

[treepop]

I just got my 1800 dlt3c today and the bios thinks its a 2000! Im happy because It tries to run it as a 2000 automatically avan though my mobo wont do 12.5x multi the chip is still locked. Whatever but I can get 150 fsb at the moment on my OLD a7v133 which is meant for palaminos anyway. at stock voltage too.

you polannen on getten a new mobo for that beast?

Just FYI:

my 1800+ dlt 0311 does 2400 at 1.675v with a Volcano7+ on medium. With water, it does 2500 at 1.725v.

On an "old" 8RDA+

can we say WOWSAS!.......2.5 at 1.725 is preaty sweet man.....

I can say for a fact that these new 1800xp 0322 do not like the vcore over 1.85.. hell, even v1.85 is a mistery why this cpu randomly reboots.

I had the exact same problems with my 1700+......what fixed the issue for me was the pin mod.....which makes it default 166......after that I hit 2.1......I dunno why this worked but it did....hope you the same luck

Yes I am Just need some money. Hmmmmm.

Oops I seem to have bumped this thread

I have ordered a new motherboard - Asus A7N8X Rev2 and it will arrive tomorrow w00t - I will soon have it up and running and I hope to find the limits of the chip then, heatsink permitting.

 

[RedDawg41]

can I ask you why u picked the Asus mobo for your OC'ing?

 

[L337 M33P]

Cos I like the layout of the Asus MB over the Abit, I am not extreme ocing, just to the max of my chip on reasonable voltage. It's really not a bad board until you put it through the grinder with extreme OCs - then it doesn't like you.

 

[RedDawg41]

cool beans... best of luck to you. (good board too).

The CPU is in the new zany plastic-coated packaging, and the die itself looks red under sunlight.

I have almost the EXACT same chip.

JIUHB0307VPMW

Got two of them from a small corner shop
in Baltimore. This one #139, and #144.
I also have a 1700+ 0307 VPMW in my other rig right now.
It's #167.
You can see all of them HERE* on my webpage.
If you click there you can see how the reflection turns from
Silver to reddish-brown the higher the production number.
With #0001 being the first from the waffer.
If I'm not mistaken on that being the production number that is. (???)

See the page lynked above.

Wow thanks for the replies - I have heard that the UPMWs like more voltage, and from some lame overclocking on my A7V333 I got to around 1.78-1.8GHz before needing to up the voltage by about 50mV.

I am going to produce a graph of minimum stable voltage against speed of processor, maybe you could do the same? The more data points the better so we can compare U's to V's. Nice OC by the way

---Edit---

New motherboard arrived at 10AM today - will return once it is installed - time to plug & pray

 

[L337 M33P]

OK XP is installed and ready - now for the OCing

First off I am still using the AMD stock HSF, so until I get better cooling (SK-7 + SF2) overclocks ain't gonna be spectacular.

more watching of this space...

 

[L337 M33P]

HOLY THREAD RESSURECTION BATMAN!

Ok, it's up to 2.092 GHz stable at 1.50v with occasional dips to 1.49v.

At this point my stock HSF is my limiting factor and I am not going any higher because temps are hitting 55c.

That's pretty damn decent with stock Vcore and especially with that stock heatsink/fan. Did yours come with the heatsink with the chinsey little copper plate on the bottom? Notice how the screws are visible - well guess what, I took mine apart before throwing it out and I found that that chinsey little copper plate isn't even in full contact with the aluminum -> fins of the heatsink - it has some smelly grey AMD phase change material between it... Possibly the worst AMD heatsink ever? Which makes your O/C that much more impressive

And out of curiosity - what is this high Voltage problem several of you have mentioned - the one that you both fixed with pin mods or the L12 bridge mod? Is this problem exclusive to the Abit NF7-S board?

Keep posting results M33P - just pump 'er!!

 

[L337 M33P]

No, it's a stock XP2000 heatsink that came with an OEM system on a palomino

It's all aluminium in design but I lapped it from slightly concave and full of milling marks to completely flat. Even so, it still sucks.

/me wants an SK-7
