Good 1115 board with three pcie slots for trifire.

r2d2 · 12 Jun 2011 at 20:42

Looking to have a i52500k and 3 6970s trifire.

Would like to over clock the i5 as well.

Which us a good 1155 based motherboard for this?

Z68 or p67

Thanks in advance.

AFAIK the p67 and z680 chipset both only have 20 lanes or something. So I think you can run 8x/8x/4x?

This one:

Gigabyte Z68X-UD7 Intel Z68 (Socket 1155) DDR3 Motherboard

Or one of these with a large enough case to fit them as they're larger than ATX:

MSI Big Bang Marshal Intel P67 (Socket 1155) DDR3 Motherboard - (Sandybridge) **B3 REVISION** with FREE Cooler Master V6GT CPU Cooler

Asus Maximus IV Extreme Intel P67 (Socket 1155) DDR3 Motherboard - (Sandybridge) ** B3 REVISION **

Or for an off the wall suggestion this one:

Asrock Z68 Extreme4 Intel Z68 (Socket 1155) DDR3 Motherboard

Asrock say it supports 3-Way CrossFireX.

You'll need a big wattage PSU to go with it all.

And be prepared for a lot of heat.

The MSI doesn't support 3-way, IIRC 3-way is only supported by NF2000 chip, which the MSI doesn't have I don't think - link

3-way SLI N/A

The OP is talking about Crossfire not SLI.

It will support triple cards in Crossfire.

This is what the overview page for the motherboard says:

ATI CrossFireX™ is the ultimate multi-GPU performance gaming platform. Enabling game-dominating power, ATI CrossFireX technology enables two or more discrete graphics processors to work together to improve graphics performance. ATI CrossFireX technology allows you to expand your system’s graphics capabilities. It allows you the ability to scale your system’s graphics horsepower as you need it, supporting up to four ATI Radeon™ HD graphics cards, making it the most scalable gaming platform ever. With an ATI CrossFireX gaming technology, the traditional graphics limitation exists no more, allowing you to enjoy higher performance as well as visual experience.

I want 3 cards in trifire.

Preferably 2x16 and 1x8 if that's possible?

Look at the specs. of the motherboards I listed.

You won't notice the difference between x8 and x16 anyway.

Don't forget to choose your case carefully if you get one.

It's bigger than a standard ATX board.

Will the corsair obsidian 800d be big enough?

Not really.

You need a case with 8 expansion slots instead of the normal 7.

Somethng like the HAF-X.

I just read a review on this board. No tri sli support. This mean no trifire support?

No n200 chip.

Completely different things.

No NF200 chip means no more than 2 cards in SLI.

That has nothing to do with Crossfire.

Oooh silly me, I thought no tri-sli implied no tri-fire

Shuld really do my homework before making assumptions like that :eek:

Sorry for the confusion!!

This board has a good layout for trifire, especially if your case only has 7 slots on the back like me.. not just that the bottom card will not hang over the power connectors and usb connectors.. I have Asus z68 pro and a ASrock z68 Ex4 but when i have the bottom card in i cant power up the pc as i cant get the power lead wires on and the power button is covered up by the 2nd card.. As for the Asrock its more stable and a better overclocker in my ap.. my 2600k is @4.8ghz all auto settings and the gskill ram is 1600mhz rated but will run at 1866mhz no problem all 16gig of it 36hrs prime.. the asus board just wont post with the overclocked ram and is a pain to get stable at 5ghz.. as for the boards running 8x8x4x pcie the 4x really doesnt seem to slow the 3rd card down, i was getting a av of 68fps on 2 cards at 5760x1200 once i added the 3rd card 6950 with 6970 bios i was getting 83fps so on average 3 cards scale really well even with the 4x cap.. sorry for the english as im on my phone.

Good link from TechPowerUp Review Database list of 1155 boards reviewed, also covers other sockets.

What board did you go for?

Surveyor · 25 Jun 2011 at 00:21

Crezzlin, just a heads up. Your signature is well oversized.

In fact it's so big all of it isn't even shown.

If you don't change it then it'll get removed.

You may use a signature (commonly used in email messages) in your posts. You can specify in your profile a signature to use at the bottom of your posts. When you post, there is an option to use your signature. A signature may contain one or more images but they must fit within a box with maximum dimensions of 400 x 75 pixels (width x height) and with a maximum (combined) file size of 20k. Images containing mostly very large words or animated .gifs will not be permitted. You may also add 1 consecutive lines of normal or smaller text directly above or underneath the image with no spaces inbetween image and text. If no images are used then up to 4 consecutive lines of normal or smaller text is permitted. Do not pad out your text lines with blanks lines. A line of text is defined as having a maximum length of 400 pixels. If you want to turn the signature off in the future, you can come back and edit your post. If you have specified a signature in your profile, the box will be automatically ticked for you.

The forum Dons/Admins reserve the right to judge individual signatures, particularly those deemed to contain material of an adult or offensive nature. If the Dons/Admins think the signature is unsuitable for a family orientated forum, then it will be removed. If the user then replaces it without making changes, they will be suspended.
