How far to push V3?

[AEboy128]

You'll see my sys in my sig, just click the link. I have the v3 1000. It has a stock clock at 125.01/125.01. I ran it at 135/135 and gained 125 points in 3dmark2000. I wanna kno how far people have ran the v3 1000 not 2k and 3k those have better memory if i remember right. The 1000 also has no type of heatsink or fan. I have 3 or 4 hs/f combo's that i could modify to fit it. If i do this what would i mount it to the gpu with. I was thinking something like epoxy or super glue. Will these work to transfer heat? Is the heatsink and fan wasted effort. What if i bought a slot cooler put the heatsink so it could pull air through the fins and out the back. What about that?? Sorry for asking so much. BTW i got 2425 in 3dmark2000 with it oc'd to 135/135. At the stock clock i got 2300. I suppose thats a pretty good gain for only a 10mhz up right??

A 1000 aye. I've only had experience with the 2k and 3k, But If you can read the code on the ram chips there's a good chance you can do a google search on the code and
decipher the specs for those chips...like how fast they are rated. For instance my V3 chips were LGS, and some other brand I don't remember, but I deciphered both in that
manner. My LGS ram was rated at 143mhz but was actully rock stable up to 174mhz. You'll have to get an OC tool and keep inching forward until you get "artifacts" to find the limit. But go in small steps.

As for the HS/HSF, I for sure would put one on if you intend to keep OCing the card.

I can't remember if there're holes on either side of the GPU to use a HS-clip on those cards or not. I think not though.

What I did...And I hate this...A single drop of super glue
on the side/edge, (not the center) will hold a [small] HSF combo in place without terribly obstructing heat xfer.
But I hate to recomend it because super glue doesn't xfer
heat and it actually will break down under heat. And it can create a air gap if you aren't careful or use too much glue. Not to mention that it's a drag trying to remove
a HSF after you've super glued it.

There is such a thing as heat-xfer epoxy, but I've never used it.

Next time i have my computer apart i'll look at the ram on the vid. card. What are the clock speeds of the stock 2k and 3k. How far can i push it with out damaging the card. The highest i've ran it is 140/140 from 125/125. I just ran it at that speed to up my score in 3dmark2000. I have quite a few 486 heatsinks and various fans laying around. I was thinking that if i put on the heatsink that it would cool the card off pretty good. Will just regular epoxy work? or do i need the heat-xfer one that you were talking about. I dont really want to put alot of money into the old card.

486HSF will work great as long as it fits and doesn't fall off. Stock 2k speed is 143mhz (but easily clockable to 174)
Stock 3k speed is 166. Stock 3.5K speed is 183 (I think)
I got the 2k to at 183 but there were some programs that had "artifacts"...backoff the speed if you get artifacts.
...Never tried epoxy so I can't say how well it works. But
I'd only place it on the edges and make sure the hsf makes good contact. I'd say thermal paste is a must especially if you use glue or epoxy because, like I said, glue can lift the HSF off the GPU.

Now im curious if compaq underclocked my 1k. What are the differences betweent the 1k and 2k? Does anyone know what the 1000 should have a stock clock speed of??
