OVERCLOCKING the Intel DP45SG

[PsyChoses]

Well I cannot, I'm in the process of restoring data from my 1TB external drive,.

my CPU Multiplier was 8.5 and still is. Why should I have changed it ? Host clock was 333 and now is 377 ....

No, no need to change it. Your settings are fine. Run CPU-Z and post a screenshot of your memory tab.

Like this:



I was just asking cos you said:

I thought it was something else before, that you were asking

Quick update.

Crysis Warhead:

2.4GHz:

CrossfireX: 20-24 fps
Single card: 17-20fps

3.0GHz:

CrossfireX: 25-40 fps
Single card: 17-20fps

Just goes to show it takes a decent processor to make crossfire shine

I was expecting some improvements at 3.0 GHz with a single card though. Strange that they're the same

Oh, and no graphical glitching in Warhead at 3.0GHz and crossfireX. PHEW!

great,awesome,just think if you had TWO 2 gig Radeon cards in......lol

LOL

great,awesome,just think if I had TWO 2 gig Radeon cards in......and uncle sam was giving me some of that bailout money to fund my eccentricities

What are you running your RAM at PsyChoses? What's ur FSB : DRAM divider ratio?

Oh, and did I mention, I'm still getting artifacting on some benchmarks and games at 3GHz with crossfire Crossfire works perfectly at 2.4 GHz, though, albeit with a graphics performance drop (10,708 @ 2.4GHz as opposed to 11,780 @ 3.0GHz). Any help guys? Do you think I need to change something from the PCI burn-in menu on the BIOS?

I had 1 HD3870 and was able to set the GPU clock to 765 and the memory clock at 1254. With 1 card it runs at x16.
I added a 2nd HD3870 in crossfire and they both run at x8 (design limitation of this board). Now I can only run the GPU clock at 685 and memory clock at 1126, otherwise there is artifacting of games crash.
This board does not run 2 video cards very well because of the x8 limitaion.
Next card will be a HD4870x2 so it will run x16.

Right, all graphical glitching has gone.

I set my host clock to 377 MHz (3.4 GHz) and memory to default and bumped up ICH/MCH voltages to 1.4 (from 1.2 I think) and processor to 1.4 (from 1.285). As Vista was loading the display froze midway. I restarted but got no display. Started panicking slightly I took the BIOS jumper out and switched it on. After one power cycle I put the jumper back in the normal position and managed to get into the BIOS. I restored everything to my 3.0 GHz 1333 MHz OC settings.

Then I ran 3DMark Vantage just to make sure I hadn't messed anything up. What do you know, no more graphical glitching in crossfire. It's working smooth as pie now. I don't know what exactly I did to achieve this...maybe it was the BIOS settings restore.

Anyway, happy that everything is working as it ought to now. I was just getting greedy trying to get up to 3.4 GHz. Blessing in disguise though, as you can see.

Yes, I've noticed that actually. When I moderately overclock the 4850 (mem from 993 to 1003 and core from 625 to 630) crysis runs for 1 minute before jamming up, and requiring a restart.

Pretty interesting philosophy yours. I'll have a look at benchmarks comparing crossfire on other boards. As far as I remember the P45 does pretty darn well. There's only one other chipset that does better. I forget which.

Edit: That's the X48. But it's too close to call. Check it out here: Performance Summary And Conclusion - Review Tom's Hardware : PCI Express & CrossFire: Scaling Explored

Edit: The x8 x8 limitation isn't a DP45SG specific one, it's a P45 chipset limitation. See here: http://www.intel.com/Assets/Image/di...ck-Diagram.gif

Here you go :





That's AFTER OCing

Awesome s***! You're running stable at 1508MHz FSB!

Time for some benchmarks dude! Futuremark - Benchmarks - 3DMark Vantage - Download

Side-note: ATI cards owners, head over to Drivers & Tools | GAME.AMD.COM for Catalyst 9.1 drivers.

Edit: It seems the driver links point to the same old 8.12 drivers atm. Keep checking!

Edit: If you're feeling a little adventurous: Catalyst 9.1 WHQL zum Download bereit - AMD Catalyst 9.1 WHQL, Download,

Edit: OK guys, screw AMD: you can download Catalyst 9.1 drivers from Sapphires website: Sapphire Technology - drivers

Edit: Sigh, I just downloaded them and they are 8.12 inside. LOL. I'm getting sick of this. Let's just wait for ATI to sort their servers out.

Final Edit: The drivers are working on ATI's site: Drivers & Tools | GAME.AMD.COM

In the BiOS it used to show 1700Mhz dunno what brought it down

Weird. It shouldn't have been 1700 MHz in the first place. Look at your FSB : DRAM divider ratio. It's 1:2, which is optimal. That means if your host clock is at 377MHz, your RAM should run at 377x2=754MHz. And in dual-channel mode that comes out to 754x2=1508MHz. So it's perfect.

Are you planning to run any benchmarks?

Well mate, here ya go a few benchmarks to keep a smile on your face













Tell me if this is good or bad

First of all, change the RAM speed in your signature to 1508MHz

You haven't posted your non-OC benchmarks so we can't really tell how well your OC is working. But just by looking at your results and comparing it with my similarly clocked (0.2GHz less, Q6600):

Processor Arithmetic:

You CPU is performing as expected: very well.

Processor Multimedia:

Our double and float scores are similar but your Int processing is through the roof. nearly 50MP/s more. Nice.

Crypt:

Very impressive crypto results. And they seem proportional to your OC. Crypto is something that really seems to benefit from an OC.

Multi-core:

Multi-core efficiencies are nearly the same, as expected.

Power efficiency:

LOL. you're getting zero for this. Very weird. Maybe speedstep is off, that is why? I'll run it on my system and let you know.

Memory bandwidth:

The numbers seem proportional to your memory OC.



Overall, your OC seems to be working splendidly. To really see how amazingly well, you'll have to run the benches at stock settings too.

Great job!

Run the memory latency test and post the results too. Also, in Sandra, if you go to the Tools tab you'll see a performance index test. Post the result from that too.

Run this as well and post the final results screenshot: Futuremark - Benchmarks - 3DMark Vantage - Download

Congratulations on a successful overclock with the Skyburg. An elusive beast at first...yet still a beast when you tame it and it comes to performing
