That's ok, anything would be nice. A lot of overclocking on this thread but hardly any scores, benchmarks or fps's. Just wondering how the 4770 do compared to the reviews I've read.

Have you read my old post at page 22 ? Crysis bench tool with 1280x1024 and 1680x1050 tests ..

Sorry must have missed it. Good stuff. Can you do crysis on dx10?

I haven't got dx10, dx9 has the same quality level and better performance so I didn't even thinked about getting Vista (or Windows ''Longhorn'' as it was called before the relase ).

Well not the same quality level but you will get twice the frame rate of DX10. Anyway, thanks for the benches.

in crysis dx9 ''HIGH'' it's equal to dx10 ''HIGH'', and you can enable dx10 effects on XP too. DX10 are 120 ''new'' Cvars on Vista but 118 of them can be enabled on XP, so itìs just a marketing related thing, a real shame.

Anyway, for the other games I hope that these dx10 exists, but someone should test such things .. Anyway we're OT, let's go back into the 4770 discussion

Well, I have used the stock cooler of the 4770 as a top support*. Then I had to sand a bit the base cooler so my screws could fit. (I used 3mm screws.. but if you find 2mm ones, you won't need to sand much).
Here a image: (Sorry for the non straight lines, I used ubuntu's **** paint and a laptop touch pad / Blue points are the place where screws must be placed / Holes that need to be sand are the upper ones)
Attachment 117702
If the screws are of 3mm, you will need to enlarge the holes from the top and bottom support. (if they are 2mm, you don't need to)

Here is the final result:

* I had to brake all "haspers" of the cooler and let it as only support, if you have time, you can build one with a piece of metal.
- If anyone atempt to make this, be very careful, as you could brake the core
- And sorry if my explanation is not clear, I 'm not english native..
- Also, I made this because I had the hr-03gt of my old and fried 4870 and because I was bored. If you only need a good heatsink, get hr-03 rev.a (4 heatpipes) or any other.
- I will post some temperatures and benches at 1ghz core 1,1ghz mem, when I get my mobo..
Thanks for reading

thanks so much, really appreciated. Well, sincerly I don't mind so much about gaming, I just would see this little baby at such high frequency, maybe with her sister (she will come later) . I was thinking about modding an accelero extreme but it seems a bit too difficult for me right now. Maybe I could handle the HR03GT so I will test this one.

I noticed a couple of things, let's examine this :

1) the heatsinks, low profile ones, just RIGHT UNDER the heatpipes, the ones upon the 2 memory modules in fornt of the core, aren't making full contact with the ram itself. Have you noticed this ? Watch out because it seems to me that the ram modules have got a too heavy pressure upon them.
2) have you touched the heatpipes itself ? They seem ''curved'' or altered. In the process of creating the 43mm holes (sanding), have you made something related to them or not ?
3) ''breaking the ore'' you mean that too much pressure on the cooler could damage it ? For sure, indeed I'm trying to find another way less intensive, I was thinking about an aluminium clip on the side, maybe even soldered to the upper part of the base if necessary, or glued.

So, tell me, at 1.1V are you rock solid at 1025MHz ? Really ? Have you tried testing it with 5 min furmark BURN test ? Check if at 980-1000MHz (core) / 1130 (ram) it's making artifacts, please note also the temperature with rivatuner statistics server, the green and black graph utility regarding the DISPLAYCOUNT/CORE,RAM,SHADER (if you have time or if you want).

Many thanks, that's really interesting because I've never seen something like this and I'm pretty confident about taking her to 1050-1150.

ps: +1 rep

Yes, I know that, the problem is that the glue has gone, and it's not hooking. I will buy a paper glue and see how it goes. But thanks anyway

Yes.. My fist mod with this cooler on the 4870, was "curving" them so the air went out by a lateral of the case.. Before puting it on the right way, I sanded it. But if you are pacient, or you have a special sanding tool, I think you won't need to "curve"

Yes, you must find the ideal presure, just to see when the cooler doesn't move

On my current card, 1.1v to make 1ghz / 1,2v to make 1025 (30min furkmakburn stable)or 1050+ any game stable.
The big problem for me, are the mems. I cannot pass 1100mhz.. for this i'm searching a non soldering mod.
Also, the day after tomorrow, I will go on vacations, a week (more or less),

Ps. with liquid nitrogen and this vmod

I supose you can get it 1200mhz or even more.. but that will be very sick xD

get an asus 4770 then, they should have got the ram of the 4890

With few heatsinks (very cheap ones) and without proper cooling on the core (75/80 degrees celsius under load, 85+ on the ram and shadercore) they worked easily at 1150,without heatsinks It wasn't possible even 1070. I haven't tested right to 1200 but I've heard that it's possible. When I'll get a new cooler like yours I will test deeper. These cards are IN NEED of powerful rams, because of the 128bit bus. In short they lack of memory bandwidht and with such high frequency on the core, the more bandwidht you throw at them, the more you obtain with real world gains.

I'm planning a crossfire at 980/1000(core)-1150(ram), on XP these babies could breach the 26.500 points with the 3dmark06, with a core i7 920@4.2GHz. Something affordable in my case.

For the moment I thank you, sir, have a nice holiday
