P35 vs. 965 spi, ram, overclocking comparison!

[Fhqwhgads6680]

Ok Guys I just got my DS3p gigabyte p35 board. I had the 965 base ds3 Rev1.3 here and thought hey, I could do a comparison between them. And wahla!

System Specs:

e4400 @ 2.7ghz for most tests
2x1gb Gskil hz's
Ds3p- p35 OR Ds3 Rev 1.3

Ok first I want to say that people should draw there own conclusions. These are just my findings, and there could be variations other than the chipset that are effecting performance

Also, This is a very untweaked xp install, and I am on a 4400 here so the cache hurts spi alot keep that in mind. Main thing is to look at times from both boards at same cpu/ram timings. Also The Same exact installation was used with the same amount of processes running. Also... my 4400 sucks lol... this thing pales in comparison to my old 6300, so thats something else to keep in mind.

now on with the show!

This is a staight boot @ 2.7ghz on the 965p only ram voltage changed:

This is the same exact bios settings straight boot on the p35

This is at 5-5-5-15 on the 965

And 5-5-5-15 on the p35

http://i206.photobucket.com/albums/bb194/fhqwhgads6680/2700_5_5_5_15_P35_2.jpg

Now 4-4-4-5 on 965p

http://i206.photobucket.com/albums/bb194/fhqwhgads6680/2700_4_4_4_5_2t_965p_2.jpg

And 4-4-4-5 on the p35

http://i206.photobucket.com/albums/bb194/fhqwhgads6680/2700_4_4_4_5_2t_P35_2.jpg

This is also 4-4-4-5 on the 965p but it had an option for "memory performance enchance" in the bios... so I gave it a go on fast. Turbo was not bootable. Gave a small increase but still not able to catch the p35:

http://i206.photobucket.com/albums/bb194/fhqwhgads6680/2700_4_4_4_5_2t_965p_fast_2.jpg

Now, I tried for the highest stable frequency on the Cpu I could. first is the 965p and I could BARELY get this board to boot this crappy chip @ 3.1ghz. Now at this frequency I couldn't even run 1m spi and I tried all the way up to 1.6v. I did get the chip to pass orthos at 3.05 ghz for 20 min before it failed but I didn't get a screen.

http://i206.photobucket.com/albums/bb194/fhqwhgads6680/highest_965_2.jpg

Now the p35, same exact chip and ram, I was able to get this thing ORTHOS stable @ 3.2ghz! I had it run for 2+hrs, but I accidentally closed orthos before I got my screenie, so I re-ran for 30 min. This is @ 1.55v Cpu temps on my Ultra 120 extreme were a little toasty in orthos reading just under 60c

So I found that not only does the p35 oc better, (150mhz better on same chip under same conditions) But it also seems to have a clock for clock advantage aswell. Not to mention the better quad ocing. Now, I know that there are probably other 965 boards that could probably catch up I am guessing, but I put this together with what I had, and since these boards are pretty similar in bios options I think its a decent comparison... Hope it helps!

Nice.

I had been wondering about the advantages of the P35 chipset. Although I had been thinking of getting a 975X board, not a 965, this was and interesting comparison.

[PanteraGSTK]

I'd like to see the same comparison using a 975 board with a p35 board. Overall, good comparison, I was wondering what the performance difference was at the same settings. You should do some 3dmark runs to see if there are differences with those apps.

[scwam]

Could you drop the mulitplier down and run the FSB as high as possible while doing 3dmark06. I'm really interested in seeing how stable the p35 is past 500fsb. Nice review btw.

[njkid32]

Good comparo! I recently went through something similar with my kentsfield. I had my X3210 running on an Abit Quad GT and it maxed at 3.2ghz and I tried everything to get it higher but nothing worked. I picked up a Gigabyte DS3R and popped it in there and I'm now running at 3.6ghz 24/7 at 1.53v 100% running WCG. All I can say is this was the smartest move for me cuz I was about to sell the cpu till I got this board.

[Fhqwhgads6680]

Yeah, I wish I had more to compare to get a good understanding of why the DS3p is better clock for clock. I'd also like to compare this with other P35 boards and see what the difference is. Yeah I will be doing some more testing on the ds3p p35 board. Its a great board, and seems MUCH more stable that the ds3 965. Just seems than its better at everything compared to my 965.

EIDT: I noticed that I had the wrong pic uploaded for the 965 @ 4-4-4-5 regular, as you can see changing to the "fast" memory performance option in the bios netter a .63 sec gain in spi. I also just realized that a straight boot at 5-6-6-18 (spd auto) on the p35 was FASTER than the 965p at 4-4-4-5 WITH the fast option.... I think thats pretty interesting....

I just got thinking about that option and I wondered if this had anything to do with that "performance level" I saw recently introduced on the p35's in memset.. I haven't done a whole lot of reading on that setting but I am intrigued because that option only exists on the 965p board....

Stay Tuned.

Great comparison. I have seen some people getting 600+ FSB on P5K. I can't wait for the X38. Now that they have DDR3 1800 that runs at over 2Ghz it will be an interesting board to SLI with and Intel is claiming 15% increase in SLI speed as well as uber high OC. Weird to hear Intel actually talk about OCing. X38 FTW!!!

[Danger30Q]

Thanks for the very straight forward comparison! I'm so sick of reading reviews on websites were they talk on and on forever about nothing. I just want results with apple to apple comparisons.

[MaK2000]

Just wanted to make sure anyone with P5K3 did read this today. http://www.anandtech.com/memory/showdoc.aspx?i=3045. This is through the roof. OCZ just released DDR3 1800 as well. It clocks over 2Ghz as well. 2Ghz System memory? FTW that is VRAM speeds. Never thought it would happen so fast that they max out the DDR3 standard and than pass it up. I think everyone should give Micron Inc some applause. ** Claps for the Micron Z9 chip ** We will see some insane speeds at some uber latencies soon. Hopefully just in time for the X38 launch.

hmmm strange.... when my team benches P965 (QuadGT) and P35 (P5K) under LN2, 965 was much better clocker.

QuadGT 965 - 529x10 (2 cores enabled) - max 16m benchable

vs

ASUS P5K vanilla - 526x10 (1 core enabled) - with 2 cores enabled max clock was under 5.2 GHz

Same Vcore, same system, same pot, same temperature :D

I had similar result
QuadGT and DFI 965-S is much better OCer than P5K Vanilla (SS and over 100MHz better on 965 that P35)
Performance in Pi 1:1 is much better on 965 than P35 too ... maybe GB wonder :D

[Bigchrome]

ent and yotomeczek....have you vdroop modded the boards? p5k is terrible for vcore but fsb is good!

[ent]

During our runs P5K was droop modded, but with droop mod enabled board refuse to run above 5GHz :D, probally because something strange was happening with Vcore over 1.8V - Vcore during stress was higher than during idle :D with vdroop enabled this diffrence between stress and idle was even bigger, that was the problem :D, on low voltages like 1.6V droop mod worked in a way it should work :D

Frankly speaking I can say that there is no diffrence in max MHz between P35 and 965, just between boards and their power circuits.

i really REALLY hope ou guys are not making any kind of a deal or comparison over less than 1 second in 1m Pi
that means absolutely ZERO.

plus the fact that once you start cranking the FSB up on the P35 sets they start geting slower and slower in terms of cpu speed vs cpu speed.

say 500 vs 400 fsb at the same cpu speed.
the chipset latencies are so freakin loose that it makes running an insanely high fsb just retarded for a cpu with an 8x or higher multi unless your going for pure cpu mhz, then of course the P35 wins as its fsb capabilities are much higher.

[caligula]

This comparison is failed from its beginning. Not a wise idea to choose a fsb-walled chip as e4xxx and a strap-problem chipset as p965.
Get a FSB 1066 CPU then redo the test. And DO read the forum (especially the one about straps on p35).

For some benchers 1 second in Pi is a huge diffrence.

P35 strap can be controlled with new Memset 3.3 and it is also very helpful feature for benching.

[ineedaname]

Good job testing all of that.

Would've been better if u showed the straps on memset tho.

read the first post again and see what he said

DS3 965 is slow

The best 965 boards to compare are DFI 965, abit quadGT or asus p5b series 1066 strap

[bassie]

What about subtimings:confused:

[Fhqwhgads6680]

I set all sub timings to their spd value. I haven't had alot of time to mess with this lately, been very busy.

And yes I know that there are other boards that would be better to try and there is alot deeper I can go with this, which I am planning on doing.

This is the hardware I have on hand...Sure I'd love to have a better chip, sure I'd love to try the top five boards of both chipsets and compare them all... but I don't have the cash or time to do that.... I am just giving you guys my comparison between 2 budget boards of different chipsets... Thanks for all those that gave support.

My S3 (cheap ds3) is always on the 1333 strap. No matter what fsb you are using.

[superray]

Seems P35 is lot faster than P965
