Has anyone seen anything anyone running an e6750 or one of the other new chips on a older 965? I've been searching but haven't come across anything yet. As a Rev 2 DS3 user, I'm definetly most interested and I'm sure others are as well!

hi
as far as i know ONLY rev 3.3 of gigabyte ds3 supports 1333fsb. maybe now any bios update is available, i dont know about it.
July 24, 2007 8:27:45 PM

What I was wondering was, if you stuck say a e6750 on a pre rev 3.3 board and overlocked the fsb to 1333, wouldn't that work? Or does the bio have to have strap, otherwise the chip won't operate?

Sorry i cant help u in this as i dont own a gigabyte motherboard. all i knew is that ONLY rev 3.3 of gigabyte motherboards support 1333fsb.

Not completely sure i'm answering you're question, and i guess it all depends on you're mobo and bios, but a quick random search turns up that an E6750 chip is supported by this gigabyte Rev 2 DS3 mobo

http://www.gigabyte.com.tw/Support/Motherboard/CPUSuppo... ssValue=Motherboard&ProductID=2424&ProductName=GA-965P-DS3

so it looks like it may be possible, but again, i think it depends on you're board and bios version

Thanks GeOMan:

On Gigabyte's site under compatible processors the site says that for the rev 2 DS3 the e6550, e6750 and e6850 are all compatible. The qx6850 is not though. Kind strange since on the rev 2 next to the FSB box it says that the FSB is 1066 while on the rev 3.3 it states 1333. I'm curious whether that means that if you plug the chip in it runs with the same multiplier but at 1066 mhz fsb, or if it actually goes to 1333 mhz. When you look at the rev. 1 of the board none of the 1333 chips are supported. I've always wondered about the differences between the rev 2/3.3, Gigabyte has the Rev 2 and 3.3 of the G965 sharing the same compatibility page. Very strange.

just overclock to 333. most(DS3 sure as hell will) boards will do it :)

I'm doing a bit of a hi-jack here. I've been wondering about nearly the same thing as the OP, although I'm interested in i975X based boards, specifically the ASUS P5W DH Deluxe. ASUS states FSB1333 support as of BIOS 2205 beta, but what would happen if a new FSB1333 C2D was put on a board that is "C2D aware", but not yet "FSB1333 aware"?

Would the board POST and detect the processor as "Unknown Core2 Processor" (or something like that) or would it not recognize the processor at all.

In essence, will we see a repeat of last year's C2D problems, that called for interim P4 or Celeron processors to be installed to do a BIOS update, so the C2D processors were recognized?

arianon: as for the Gigabyte website, they've always been a bit on the funny side when it comes to having the correct drivers for their chipsets, generally if i have and nVidia chipset i'll DL the drivers from nVidia and the same with intel, i've had 3 Gigabyte boards so far and loved every one of them, but the drivers on their website are often old or just plane and simple the wrong drivers like right now on their site the drivers for my current board are the nVidia Window NT drivers not the XP drivers, and in games i did notice a couple more FPS once i got the correct drivers from nVidia. the only thing i really trust the Gigabyte site for is their sound drivers and their bios. As far as CPU compatability I'd probably trust them since it's all up to the bios.

Now as for FSB speeds i have no clue, Intel and board manufacturers have so many variants of cipsets supporting/not supporting 1333mhz that I've given up trying to keep up, maybe try giving Gigabyte customer support an email, although from experience Gigabyte customer support is a bit of myth, I've never heard back from them.

Azrael-

That is exactly what I was wondering, trying to decided between a q6600 and a e6850/e6750. Although if my motherboard won't take the latter makes it an easy decision :) 

GeOMan:
I feel the same way, this is my 2nd gigabyte board in a row and loved them both. I sent a msg to Gigabyte about the wierdness of their site, and how my board (rev 2 ds3) wasn't even listed when you go to support and try to find it, they sent me a link to he correct page. You'd think they'd want to fix their website...

This may help u , i have a GIGABYTE 965 DS4 , REV1.0 , and i asked gigabyte , and here is the answer and the questions :

Question :
HI, I am going to buy a 1333MHZ cpu soon , and i have gigabyte 965pDS4 REV1.0 , will it support 1333MHZ with a BIOS update or no?
thanx

Answer : Dear Sir,

Thank you for your kindly mail and supporting GIGABYTE.
About the issue you mentioned in your earlier mail, the CPU is still under developing, once the CPU is launched, will update CPU support list on our website for reference.


Question : thank you , well i live in UK , and an online shop has those 1333MHZ FSB CPU's in stock ,and i want to buy them , so what shall i do ?

Answer : Dear Sir,

Thank you again for your kindly mail and inquiry. In our opinion, please make sure the CPU is official and boxed Intel CPU and at this moment, as we know, FSB 1333MHz CPU is only Engineering Samples and we do not recommend you using such CPU on GIGABYTE motherboard and will not gurantee the CPU will work on GIGABYTE motherboards and any other results.

Question : Thank you again , well Core2Duo E6750 is available for purchase in this site :

http://www.overclockers.co.uk/showproduct.php?prodid=CP... 01&catid=6&subcat=793

So as you see it is availabe and thats the CPU i want , so will my MotherBoard support it ?

Please gigabyte , many other manufactures have released a BIOS for their 965P series to support 1333MHZ CPU ,

Looking forward hearing from you


Answer : Dear Sir,

Thank you again for your kindly mail and inquiry. We are sorry only rev 2.x or above MB supports FSB 1333 CPUs.

Question : Oh , i had to buy that ASUS mobo instead of mine , at least that supports 1333mhz cpu's ,
very funny , rev2 and rev3 will support but rev1 doesnt , u made me regret buying gigabyte motherboards EVER , that's the first and the last Gigabyte board i ever have!!


Answer : Dear Sir,

Thank you again for your kindly mail and inquiry. In fact, when you install FSB1333 CPU on rev1.x motherboard, you have to set FSB speed manually. Only rev2.x and 3.x will set proper FSB speed automaitcally. Thus, we do not highlight FSB1333 CPU on our website because of the reason.



When i wanted to buy my gigabyte ds4 . i could buy ASUS P5B DELUXE , and that supports 1333MHZ CPU's
July 27, 2007 12:58:46 PM

arianon, I'm having more or less the same decision-making problems as you. Since the E6600 apparently isn't available here any longer and the E6700 costs more than even the E6850, I've been looking long and hard at the Q6600 which uses FSB1066. However, I believe I won't need 4 cores for the foreseeable future and why waste electricity and generate extra heat on some something I don't really need right now.
It's a real shame that manufacturers like ASUS, Gigabyte, MSI and the like aren't more forthcoming about the capabilities of their products. I've earlier tried contacting ASUS on another matter and the replies were nonsensical, if they came at all.
July 27, 2007 5:02:34 PM

Hope this isn't too off topic. Trying not to create thread clutter.

If I buy the e6850 with the 1333 FSB, will it work in my Intel D975XBXLKR Mobo which clearly states a 1066 FSB (assumably the cpu would run at 1066)?

Do you think I could oc the mobo FSB to 1333? (suppose I should just poke around in the BIOS when I get home and answer it for myself).

Probably an easy question for you guys! :) 
July 27, 2007 5:57:13 PM

ga p965 ds3 rev 1.3 and up support upto 2000fsb, sometimes even higher. when intel says that you need a motherbord that supprts 1066 or 1333 fsb they just telling you that your mothers needs either fsb@ 266 or fbs @ 333. in other words.. you're fine.
July 27, 2007 6:15:16 PM

from my understanding and that email to gigabyte posted, it sounds like you just have to set the FSB manually, rev2/3.3 will automatically adjust for the speed.

so if your running 1066, just OC to 1333. i have a ds3 rev 1 and it runs 1333 FSB and faster just fine.

I think you meant to say that they are 'capable' of 2000fsb. The manufacturer does not actually 'support' 2000fsb speeds.
July 27, 2007 7:50:55 PM

look when manufacture says "support xxx fsb" they mean they support chip that do xxxx fsb. if there was a chip with a 1600fsb the ga 965p will support it because thats only actual 400fsb
July 27, 2007 8:13:42 PM

No, P965 supports 1066 and now 1333 with BIOS update but these are the CPU rated FSB, not that / 4. The intel board from 4 yrs ago support 800MHz FSB, meaning 200MHz bus & 400MHz ram, not 800MHz ram. So without any further updates no 965P does not support a 1600MHz FSB.

I have seen two threADS where someone mentions running 1333 fsb (E6X50 chips) on DS3 rev 1 boards. So so far the future is looking good for P965 users.

You can probably overclock to a 1333 FSB speed but Intel is not planning to add the new uCode to support that new processor in the Bios as far as I have heard. The board has been EOL.

As far as I can tell all of the new Bearlake Intel boards will run the new E6x50 processors. I have not even found any evidence that the Bad Axe 2 is going to support the new E6x50 1333 FSB processors. Intel has not officially supported any speed higher than 1066 for the 975 chipset.
July 28, 2007 2:11:10 AM

you need to check bios upgrades for each mobo - i do not think the 965 chip set has native settings for 50 series chips

i was pretty sure the mobo's with old bios would not recognize the chips?
July 28, 2007 5:12:29 PM

All I know is most of the 680i boards can support it.


Pretty much any high end board can.
July 28, 2007 7:24:16 PM

I was hoping a 1333 CPU would work on my rev 1.0 DS3, but it doesn't.

I just bought a E6850 and it will not recognize it. I set my E6400 to 8x333 and it will not boot. Starts, reboots, and that's it. Fans spin but no beep, no Windows. Perhaps, it needs to see that 9 multiplier.

what the hell?? the cpu rated fsb IS the "/4". the new p32 and the p5's say "1066 & 1333 fsb" but they also support 800mghz- 1200mghz ddr2 ram but can also do 800mghz - 2000+mghz ddr3.
July 29, 2007 8:48:55 AM

cd14, dumb question, but have you updated you're bios? that may be the route of you're problem, since the latest bios versions will have support for the latest chips. If you have updated you're bios then I'll agree with you and say you got unlucky when buying a Rev 1.0

Hey GeOMan, I have the F12 BIOS installed. Gigabyte says no native 1333fsb support for ver 1.0 and I couldn't get the E6850 to boot either. No matter what multiplier or fsb I used, it just wouldn't boot. The BIOS doesn't show the 9 multiplier with the E6400 installed so I couldn't set 9x333.

I took it back and got a Q6600 for the same price. I was hoping to get > 4 ghz with the E6850 with this board since I got 3.6 ghz on my E6400. I bought it with my E6400 a while ago, so it's the initial version.

It's a lot tougher getting the Q6600 to overclock...so far 3.15 at 1.350v. I need better cooler to keep the temps down.
July 29, 2007 9:21:00 PM

Ok, well then that's plane just unlucky, just go's to show that buying a board with "future proofing" features is always a bit hit and miss.

cd14 hope you get the over clock you were hoping for with the Quad, and when all is said and done, the Q6600 and the E6850 are both monsters in terms of performance even if you don't over clock them, sure as hell kicks my AMD 4200 X2 in the teeth (;
July 30, 2007 3:09:22 PM

cd14:

Sorry to hear about the e6850 and your board. I think what happened with the p965s is that the 'circuitry' changes in the rev. 3 are in the rev 2 as well. Whether or not there is a strap for 1333 has yet to be tested on the rev 2. But when you look at the CPU compatibility chart, even though all the revisions are running the f12 bios, only rev 2 and up have the new fsb 1333 chips listed. Although the rev 2 can't handle the qx6850 (according to their charts). I'm tempted just to buy a 6550 to confirm this.

I recently purchased a 6550 for a different computer. It didn't work on that motherboard, so I tried it on my DS3 Rev 1 board with no luck.
The board is capable of overclocking a 6300 to a 400mhz FSB (3.2Gig, same multipier) without a problem. I tried the latest f12 BIOS and setting it manually to 333Mhz FSB but it just turns on and starts the fans spinning flat out and that's it.
It looks as if it would work if they set the BIOS to start the 1333 chips at 1066 until they got to the POST then run at the manually set FSB? For now though it looks like I'll have to take it back (if they will accept it seeing as there is actually nothing wrong with the chip and the packaging is open), or buying another motherboard .... sigh. :cry: 
August 8, 2007 7:55:07 PM

Don't know if anyone besides me cares, but I got an answer from ASUS regarding my question how a Core2-capable, but not yet FSB1333-capable board (I specifically asked about the P5W DH Deluxe) will cope with an FSB1333 Core 2.

The original reply was in German, so for those of you not familiar with the German language I'll do a quick translation afterwards:

"Die sicherste Variante wäre eine ältere CPU einzusetzen und dann das benötigte Bios Update zu tätigen. In der Regel wird bei einsetzen einer nicht unterstüzten CPU die Meldung uCode loading error ausgegeben. Man kann durch drücken der Taste F1 aber weiterarbeiten und dann das Bios Update machen. Dies ist aber keine Empfehlung."

So, in essence they recommend that the board's BIOS be flashed using an older CPU that's recognized by the board's current BIOS. Usually, though, the board will show the message "uCode loading error" when used with an unrecognized CPU. At that point you can press F1 to continue and perform the BIOS update (that introduces FSB1333 compatibility). They do not directly recommend this procedure, however.

The question remains, do I dare do it? That Q6600 is still tempting. Not only is it cheap, but there are no FSB1333 issues. On the "con" side, I do not need 4 cores, and neither does most available software. Still, all 4 cores run, which makes the CPU use more power resulting in more heat on top of that...
