New Core i7 builds, but big freezing problem on main client! Pls help!

Link does not work.

These sweeping statements about I7 RAM speeds are not exactly true.
I7-920 (OP's model) doesn't offically support Memory speeds above 1066 and doesn't have internal mulitpilers to get to any faster speeds. You can overclock the processor and get higher effective speeds.

I7-965 does support much faster RAM speeds, it can go faster then any RAM on the market today.

Hi guys!

This is really interessting, i have had some problems with my new computer and wow aswell. It kind of feels like my new computer is slower and not as good as my old dual core computer.

my current spec is:

Intel® Desktop Board DX58SO
CORSAIR XMS3 4096M DDR3 Kit 1333MHz, 2x240 DIMM, DHX (TW3X4G1333C9DHX)
WESTERN DIGITAL CAVIAR GP 500GB SATA2 7200RPM 16MB (WD5000AACS)
INTEL CORE I7-920 2.66G 8M LGA1366 BOX (BX80601920)
MSI GF GTX 260 PCIE 896M GDDR3 2X DVI OC (N260GTX-T2D896-OC)

At the moment my i can only use 2Gb of memery, when i put in the other memeory my pc wont boot. Tried last night again after running with 2GB for the last 2-3 months.

On intel site it says:
What is the maximum frequency for DDR3 memory when used with Intel® Core™ i7-900 processor series?

These processors support DDR3 memory with a maximum frequency of 1066 MHz. If faster DDR3 memory is used (such as 1333 MHz or 1600 MHz), it will be down-clocked to operate at 1066 MHz.

I can not find any place on intel.com if my RAM is supported or not?

My motherboard support something like 3 chanel something something, so I think i want to try 3 x 2 GB of RAM and install win 7 64, what do you think?

By the looks of your post, you're only using a dual channel DDR 3 kit, when the i7 uses triple channel kits. Have you only got 2 RAM moddules?

Ive had my computer for less than a week now and have already run into a similar problem.

I have an i7 920 as well. I was playing WoW with no issues. Then I ported my main character to Dalaran, and now it freezes if I try to log in to ANY characters, so I am not really sure what the hell that is about.

Currently trying to reinstall WoW, I really hope I dont have a hardware problem...

Dal is a bitch on multi boxers. All I can say about the I7 is I have built a ton of them for various clients and time and time again when it was random crashes/freezes it was caused by the RAM.

I am not saying you cannot get off list RAM to work. I am just saying you cannot get consistant results with off list RAM. I got no reason to lie about it and can make sweeping statments about RAM and I7s because this is what I do to pay my 4 mortgages and feed my two children.

If you are running an I7 and it randomly freezes then make sure the RAM is

1. compatible with the mobo
2. compatible with the CPU
3. running in triple channel mode

You can run memtest all day long and it will tell you your RAM is fine and it probably is. It is just not fine with the I7. The only way to truly test it is toss the ram in and run Prime95 on it.

The I7 has no off CPU RAM controller that can speed up or slow down RAM or mess around with voltages. It is done all right on the CPU and it has very tight specs. I don't know what else to say to convice people of this.

Also if you are going to Multibox and goto Dal I would say at least 12 gigs. Will it run on less sure it will but it will run like crap. RAM is cheap enough right now that if your mobo can handle it then there is no reason to not have as many gigs as the I7/operating system can handle.

TBH get some good on list like 1033 RAM and your I7 will scream right along. DDR3 is already so fast and if you are only playing WOW you will not notice a difference using faster RAM.

I hope you guys get the problems worked out cause I7s are smoking fast when configured correctly.
