Memory Problem With Replacement CPU: i7 3770

[SWDescent]

Hi, I'm new to this forum but not to computers. I've built many systems and rebuilt many systems, even laptops and consoles and have had great success...up until recently. About 3 months ago I built a new i7 System to replace my aging core 2 duo, which had a sad little MSI Geforce 9800GTX+OC (could you make a model number longer?) and was starting to struggle with modern games.

 

So I built a pretty moderate system:

 

i7 3770 with a Hyper 212 Plus Cooler

MSI Z77A-GD45 (Now replaced with a Z77A-GD65)

8GB (2x4GB) Mushkin Blackline DDR3 2400
MSI Radeon 7870 GHZ OC

Corsair HX850 Modular Power Supply

Western Digital Black Edition 1TB
Asus DVD-RW

And it started out great, and I was just going to live with the onboard sound, but whenever I started anything 3d intense there was this terrible buzzing sound from my speakers, tried two different sets of speakers (always making sure there wasn't any wires crossing over them even) as well as two sets of headphones, and the sound was always there, it litterally sounded like a dirt bike engine revving up and down as the gpu usage was ramping up and down, and no matter what I did the sound wouldn't go away, I've swapped the motherboard for a identical replacement, then even upgraded to the GD65 motherboard and it was still there (which I thought that would get rid of it, much nicer sound chip and further isolated from PCI-E Slot). I then proceeded to replace each part as I thought would be causing the trouble. I ended up replacing the Motherboard, Video Card, And Lastly the CPU (I also tried a different power supply to make sure it wasn't defective either: PC Power & Cooling 750Watt). And right before the cpu was replaced I noticed when the phase load changed on it, the cpu itself was making noise. I then replaced that and it's still making the sound, though somewhat less noticeable compared to last time, but still there.

 

I have found out that if I use an external sound source (usb) the sound is no longer in there and have solved that for now, but the new problem is my Ram. The old cpu that was making noise would allow me to run the ram at the full 2400mhz, now I can only hit 2200mhz, any higher and the computer won't even post, and the bios goes into a safe mode of it's own and I have to tweak the ram settings. I went so far as to try to manually time all of it from Mushkin's product listing of the specific ram with no success.

My Question is, do I have another defective cpu (which I think intel won't warranty anyways since I'm running it above the spec'd 1600mhz they list is supported for anyways) or what's going on with this monster? I've never had a problem like this before and The Ram/Cpu tests fine on Prime95 and Memtest86+ So I've pretty much ran out of ideas.

 

Thanks for any responses in advance.

this may not work but try boosting up ram voltage by .15 . that helped me with my ram problem

 I'm running it above the spec'd 1600mhz they list is supported for

There you have your answer. Intel chips are guaranteed for that RAM clock. Any higher is considered overclocking and as always with overclocking: your mileage may vary.

 

PS: love the 9800GTX+OC! Used to have that as well :D

1. Wait for intel to test 2.4 Ghz/2400 MHz

2. Over clocking is like a game a cards there is a rule and a trick there is good luck and bad

3. Just make sure you really know the benefits and differences of each pot

4. I love the old nvidia GPUs mostly because I had a 8400 GS

So I tried upping the ram all the way to 1.7volts and still no post, I guess this cpu just can't handle the memory running at that speed like the last cpu did, at least this one doesn't have ic's making squealing noises at me loading programs... :/ Thanks for the help though, At least it's running stable at 2200mhz which is still better than 1600mhz.



Also I'm still using that beast of a 9800gtx+OC in my HTPC, which unfortunately is restricted by the ancient Celeron 1.8Ghz Socket 775 Cpu in there. Thinking of upgrading my wife's Core2Duo with a new AMD A10 or something and Swapping the Cpu/Mobo/Ram from her current setup, then at least I can game on my 55" TV :)
