Seeking Compatible DDR3 for EP45T-UD3P

[dan61psu]

Hello -

I am trying to find a dual channel, 2x4GB DDR3 RAM kit for my motherboard (EP45T-UD3P rev 1.0 from Gigabyte).

I tried this kit: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL http://www.newegg.com/Product/Produc...82E16820231314

But the machine wouldn't even post to BIOS at all. After some research, this kit is just not compatible it seems, so I am RMA'ign it to NewEgg.

I have read a bit and found some folks who used this kit as of 2009: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBRL http://www.newegg.com/Product/Produc...20140517095911

Can someone confirm compatibility or reco a compatible DDR3 kit for this motherboard? I am do not intend to OC heavily, or at all, just want to up to 8GB from 4GB. here is my current setup, which is now on Win7 (was XP).

MoBo: Gigabyte GA-EP45T-UD3P Rev 1.0 (F7 BIOS)

CPU: Intel Core 2 Duo E8400 @ 3GHZ

CPU Cooler/Fan: OCZ Vendetta 2

Current RAM : OCZ Reaper Series PC3 14400 (PN OCZ3RPR18004GK) (8-8-8 @ 1.9v) - 2 x 2GB

GFX Card: GeForce GTX 280

PSU: PP&C Silencer 750 Quad

Case: NZXT Tempest with 3 intakes and 3 exhausts (big 'uns)

Thanks!

Yes, the DDR3-1333 model should work. You can not use DDR3-1600 because your CPU FSB is 1333MHz.

Thank you

THanks - will give it a shot

[dan61psu]

GSKILL TECH - I tried and was rewarded with the same behavior. NO BIOS, no System LED on front of case, CPU fan wont spin. Are you sure they are compatible?

[emissary42]

Did you get a single sided kit (ICs only at one side of the modules)?

[dan61psu]

i bought what i posted int he link above...i cant say for certain due to heat shield but it looks like there are chips on both sides...from the shadows i can see anyway

[emissary42]

if you look at the module from the side and/or below you should see it. If there is chips on both sides, then start with only one module installed. Does your system startup then, at default settings?

[dan61psu]

no it does not. i tried just one module in multiple slots to make sure it wasnt slot problem or something.

[emissary42]

Thats odd, most 2Gbit ICs and modules using them should be compatible (i have tested the most common variants @ X48). You could try updating to a newer bios (don't forget to do a full manual CLR_CMOS), but thats more or less a shot in the dark on my end.

[dan61psu]

I am going to try tonight manually setting the RAM clock speed to 1066 in the BIOS before installing the modules...also manually setting DRAM V to 1.5 instead of leaving it on Auto. See if that gets me a boot...

[dan61psu]

no luck...GSKILL TECH - any thoughts here?

Tried the following:

1. setting to 3.20B only and 1.5 DRAM --> no boot
2. Setting to 3.20B and manually setting timing of 9-9-9-24 with 1.5 DRAM --> no boot
3. Setting to 3.20B and manually setting timing of 9-9-9-24 with 1.5 DRAM and clocking FSB up to 400 while down clocking CPU multiplier to 2.8GHz--> no boot

in between these attempts, the old RAM booted every time, and its max volt is 1.9 on the sticker

GSKILL TECH - I would really love some help since you claimed this RAM would be compatible....if I have to RMA it, it comes out of my pocket. (lets hope not) Thanks.

[GSKILL TECH]

Maximize the tRFC setting for DRAM timings. If you can, post a picture and I can see if anything is incorrect.

Thank you
GSKILL TECH

[dan61psu]

I will try that.

[dan61psu]

No luck setting tRFC all the way up. Pics of M.I.T coming...
