Hello.

Not sure if this is the correct location for this post or not.

I didnt see a 'memory' specific section (OC only section for memory).

 

I am trying to get my system stable.

It will crash at 'mobo' default settings of 1333 on the memory while gaming.

If I use EPP settings, it sets it memory to 1600 (unlinked), and crashes on desktop load.

If I put the memory on ANY setting over 1333, it crashes on desktop load.

 

So, basically, it crashes on 1333 AND on reference 1600.

 

Can anyone help?

 

Thanks.

Download Memtest86+ V2.01 from--->

Download CPU-z from

For your DRAM to run at 1600Mhz you must set your FSB to 400Mhz to achieve the 1:1 ratio that Intel demands as a minimum. Enter your BIOS. Load setup defaults, save setup defaults and set to these values:

 

 

Extreme Tweaker

CPU Level Up = Disabled
Memory Level Up = Disabled 

AI Overclock Tuner = Manual
CPU Multiplier = 10
FSB - Memory Clock Mode = Unlinked
FSB (QDR) = 1600 (400)
MEM (DDR) = 1600 (800)
LDT Frequency = 5X
PCIE BUS, Slot 1 & 2, Mhz = 100
PCIE BUS, Slot 3, Mhz = 100
SPP <--> Ref Clock, Mhz = 200

Memory Timing Section

tCL (CAS Latency) = 9
tRCD = 9
tRP = 9
tRAS = 24
Command Per Clock = 2T

Advanced Memory Settings

tRRD = Auto
tRC = Auto
tWR = Auto
tWTR = Auto
tFAW = Auto
tREF = Auto

Over Voltage = All Set to Auto

CPU Configuration

CPU Internal Thermal Control = Auto
Lmit CPUID MaxVal = Disabled
Execute Disable Bit = Enabled
Virtualization Technology = Enabled
Enhanced Intel Speedstep(tm) Tech = Disabled

CPU Core 2 = Enabled
CPU Core 3 = Enabled
CPU Core 4 = Enabled

[b]System Voltages[/b]

CPU Core = Auto
CPU FSB = Auto 
Memory = 1.7v
nForce SPP = Auto	
nForce MCP = 1.55	
HT nForce SPP <-> MCP = Auto

 

Run Memtest for two full passes. When assured of stable DRAM, then enter Windows and run CPU-z. Please post screenshots of the CPU-z CPU, Memory and SPD tabs. If you have memory issues, remove one stick and Memtest with one stick in the slot closest to the CPU. Remove the stick and test with the second one in place.

 

Results?

I will run memtest tonight.

 

But, again, I cannot go over 1333 without the computer crashing on bootup.

 

I cant even do 1334 on the memory.

 

And a cpu-z screenshot should not be warrented, with all of the bios info I just posted (which shows 10 times more than cpu-z does).

 

But, ok.

Please make sure that you have the latest bios and load setup defaults and then set the memory Voltage to 1.8-1.9 Volts then set the timings manually to the tested settings for the specific module you have, and test the modules one at a time with http://www.memtest.org to be sure one is not failing. If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test.

Does it show the SPD ROM readout for speed and timings? I don't see that anywhere. Does it show the SPD JEDEC readout? I don't see that anywhere either.

 

Set to the values shown, boot to memtest and test. Try this with a single stick. Remove the stick and try with the other stick. Same results? Crash on bootup with either stick?

DerekT.

Sorry, I did not mean to sound like I was being a dick.

I was seriously wondering why.

Now I know why. :)

Thanx.

 

Here is a cpu-z shot (the exact memory I have, but not mine since I am at work) of the spd tab.

I now notice that it has looser timings at 1333, but less voltage also.

 

I will run memtest when I get home.

1 time on both sticks at the same time?

Then, if there are errors, 1 stick at a time?

I will also try booting at 1600 per specs with only 1 stick.

 

Thanks.

Yeah, I hear what you are saying.

 

But, if the memory passes memtest w/o issue, is another pair going to be the same?

IE: Will another pair enter windows at the specified speed and voltage, or will I just be out of a computer until I get the next sticks and have the same problem?

 

:(:

Let's go about this a different way. Let's allow the BIOS to select.

 

 

Extreme Tweaker 

CPU Level Up = Auto
Memory Level Up = Auto
CPU Multiplier = 9
FSB - Memory Clock Mode = Linked
FSB - Memory Ratio = Sync Mode
FSB (QDR) Frequency = 1600
Mem (DDR) Frequency = 1600
LDT Frequency = 5x

Memory Timing Section 

P1 = Auto
P2 = Auto
tCL = 9
tRCD = 9
tRP = 9
tRAS = 24
Command Per Clock = 2T
tRRD = 1
tRC = 35
tWR = 10
tWTR = Auto
tFAW = 35
tRD = Auto
tRTP = Auto
tRFC = Auto
tREF = Auto

Over Voltage

CPU Voltage = 1.36v
Loadline Calibration = Enabled
CPU PLL Voltage = 1.55v 
CPU VTT Voltage = 1.25v
Memory Voltage + 1.8v
NB Core Voltage = 1.45v
SB Core Voltage = 1.55
CPU GTL_REF0 Ratio = -29mV
CPU GTL_REF1 Ratio = -32mV
CPU GTL_REF2 Ratio = -32mV
CPU GTL_REF3 Ratio = -29mV
DDR3 CHA1 Ref Voltage = Auto
DDR3 CHA2 Ref Voltage = Auto
DDR3 CHB1 Ref Voltage = Auto
DDR3 CHB2 Ref Voltage = Auto

CPU Configuration

CPU Internal Thermal Control = Auto
Limit CPUID MaxVal = Disabled
Enhanced C1 (C1E) = Disabled
Execute Disable Bit = Disabled
Virtualization Technology = Disabled
Enhanced SpeedStep Tech = Disabled

All CPU Cores = Enabled

Spread Spectrum Control = All to disabled

 

Retest.

Nope.

 

Got homr e tonight, powered on the machine, hang right after boot.

 

RAMGUY:

I bought these at newegg.

I would like to return them for a refund and get another set of memory.

I put in for the rebate already though.

IS there a way to stop the rebate and be able to return these to newegg?

 

Thanx.

I am sorry but I have nothing to do with Rebates and would not have any way to help with that. They would be done by a third party.

And I am not sure the reseller will take them back if you cut out the bar code for the Rebate.

But we can replace them if you like, please use the On Line RMA Request Form and we will be happy to replace them.

 

Also did you try the settings DEREKT suggested with the modules in the black slots?

Dave, I found your review at the Newegg review page. Have you resolved this issue?
