Re: X48T-DQ6 issues with TW3X4G1800C8DF

Similar pain here with only 4x1GB Corsair with Intel Q9450 on 64bit Vista. I tend to but a load on it. Memory tests (Vista) have not failed.

First MB lasted 32 days. BSODs. Wrecked the controller which took out new HDD.

Frys would not not replace mb. Had to buy a new one and will get GB to replace first one. I do think the F7 bios had more issues with my system than F6 so went back there. Not setting turbo in bios.... Would like to hear what others have seen.

Re: X48T-DQ6 issues with TW3X4G1800C8DF

You should try this for a Quad >>>
CPU/PCIEX Clock Driving Control [800-900mV]
CPU Clock Skew Control [50-150ps] << I would start with 150 and work down
GMCH Clock Skew Control [50-250ps] << I would start with 250 and work down

And you FOR SURE need to add +0.1 or +0.2 MCH voltage for 8GB, +0.3 may even be needed, +0.1-0.2 is recommended just for 2x2GB.

And you likely should/need to manually set the Ram Voltage to it's default. The boards default is 1.5V, most DDR3 is 1.8V. Similar to DDR2 JEDEC Standards of 1.8V and most using 2.1. So just check your ram sticker and see if you need to adjust it to 1.8V. See below

I found this at Corsair about those modules >>>
This memory has been verified to operate at 1800MHz at latencies of 8-8-8-24 at 1.8V VDIMM. >>>

http://www.corsair.com/_datasheets/TW3X4G1800C8DF.pdf

And for 8GB at that speed you may also need to set CAS to 9, so 9-8-8-24. But you may not need this once you add the needed MCH voltage, and set the DDR3 voltage in the BIOS

Re: X48T-DQ6 issues with TW3X4G1800C8DF

It appears that upping the voltages has solved most of the problems and I have isolated the failure to store BIOS settings to Xtreme Memory Profiles and System Memory Multiplier settings.

At the the following settings the system runs stable

M.I.T. Intelligent Tweaker (MIT)
Robust Graphics Booster [Auto]
CPU Clock Ratio [8]
Fine CPU Clock Ratio [0.0]
CPU Frequency 3.2 (8 x 400Mzh)

Rank Write to Read [7]
Write to Precharge [14]
Refresh to ACT [100]
Read to Precharge [7]
Static tRead [9]
Static tRead Phase [0]
Comand Rate [2]

Clock Driving and Skew Control

CPU/PCIEX Clock Driving Control [900mV]
CPU Clock Skew Control [150ps] {unstable with <}
GMCH Clock Skew Control [200ps] {unstable with <}

System Voltage Control

DDR3 OverVoltage Control [+0.30V]
PCI-E OverVoltage Control [Auto]
(G)MCH OverVoltage Control [+0.200]
CPU Voltage Control [1.30000V] {in Auto BIOS sets to 1.5 which runs chip too Hot!!}

The system now shuts down and starts normally.

However with Memory settings set to anything other than these...

Xtreme Memory Profiles (X.M.P. )[Profile1] and
System Memory Multiplier (SPD )[Auto] and
Memory Frequency 1800 1600 <--- {Dimmed Out}
DRAM Timing (SPD) [Manual]

....the System continues to power down, reboot, and load default settings, 7.5 x 450 @1333.

Also any attempt to Over Clock makes the system becomes unstable and locks up after a few minutes. Any attempt to Overclock above 420FSB causes to system to lock up immediately!

Any suggestions for getting the system to overclock??? All I want is some minor overclocking for now with the FSB to 8x 425 @1700.

Here's an attachment showing the system normal at 8 x 400

Another minor issue I'm having is with the Graphics cards. I'm running two ATI-Radeon 4850 (Gigabyte) in both PCIe Slots powering 4 monitors. On boot-up the cards see only 1 monitor each. Every time I start I have to go into settings/display and turn off all but one monitor to get the others to boot. Once booted all works fine, also in sleep mode all monitors work OK. Is this a Vista 64 problem? A ATI driver problem, or Motherboard problem??

Re: X48T-DQ6 issues with TW3X4G1800C8DF

The main thing is with Profiles enabled that disregards your timings choices if you make any, and any MCH latch or Ram Multi you set.

So you need to decide if you want to use them or not and if you want to overclock or not. Which I see you do want to overclock, and based on those settings listed above I would think XMP profile sucks. I would manually set it all myself. Before you start thinking about or overclocking PLEASE Set this to >>>
PCI Express Frequency [100]

That would likely be a ATI Driver issue, have you added PCI-E voltage? If not you can try +.1 or .2

Here is where I would start with 8X425 >>>>

Performance Enhance [Standard]

Extreme Memory Profiles [Disabled]
System Memory Multiplier [4.00]
Memory Frequency [1600]

Dram Timing [Manual]
Standard Timing Control
CAS [8] << try 9 for now if all fails. 8GB is ALOT of stress on NB and system
Dram RAS to CAS# [8]
DRAM RAS Precharge [8]
Precharge Delay [24]

Advanced Timing Control

ACT to ACT [7] << 4-7
Rank Write to Read [7] << 9-14
Write to Precharge [14] << 12-16
Refresh to ACT [100] <<< 65-75 (May actually need more but 100 is excess for sure)
Read to Precharge [7] << -4-8
Static tRead [9] <<< 7-12
Static tRead Phase [0] << Leave on AUTO, Zero, or 1-31
Comand Rate [2]

Clock Driving and Skew Control

CPU/PCIEX Clock Driving Control [900mV]
CPU Clock Skew Control [150ps] {unstable with <}
GMCH Clock Skew Control [200ps] {unstable with <}

System Voltage Control

DDR3 OverVoltage Control [+0.30V]
PCI-E OverVoltage Control [+.1 -.15 -.2] << For stability for your 2x cards
(G)MCH OverVoltage Control [+0.200] << may need more with 8GB (And a Fan on NB)
CPU Voltage Control [1.30000V] << may need more as you know for more

Re: X48T-DQ6 issues with TW3X4G1800C8DF

I also have a X48T-DQ6 with Q6600 and hyper x 1800 looks like my memory is going at 1066? Ie tryed change fsb and little of this and little of that, but always go back to stock, i dont have a clue why.

I was not trying to overclock i just want my memory to go at the normal 1800 now its about 800 to slow and that sucks.

Should i aybe change processor to a E8500 with 1333 so the memory and processor works at the same fsb.

What do you think computer gurus?????

Thanks in advance......

Re: X48T-DQ6 issues with TW3X4G1800C8DF

You need to change the Memory Multiplier in the BIOS to make the ram faster. And yes, you MAY have to overclock your CPU as well to get there.

Please post your FULL specs (Like 2x2 or 2x1 ram mostly) and Fill this in with your settings. And I will suggest some back to you to get your ram clocked a little higher >>>>

Re: X48T-DQ6 issues with TW3X4G1800C8DF

This is the exact memory i use......Komplett.se - Kingston DDR3 HyperX 1800MHz 2GB, Kit w/two HyperX 1024MB DDR3, CL8-8-8-24

ill try the settings as soon as possible......if i wanna go higher and maybe overclock like you said......whar will the settings be in bios if i wanna come close to like 2,70 ghz or 3ghz and near 1800mhz on the memorys???
Thanks for your answers, very kind:)

Re: X48T-DQ6 issues with TW3X4G1800C8DF

Edited above post, your ram is 1.9V Ram.

The above post is at 3.0Ghz, incase you did not see (9x333=2997)

For 3.0 with higher ram speeds you will have to switch back down to the 8 Mutliplier for your CPU. To get 1800 Ram speed you will need to use the 7 multi, or run your CPU at 3.6 (8x450), which your chip/cooler may or may not do.

I will also post a 7 Multi table below

Re: X48T-DQ6 issues with TW3X4G1800C8DF

Hey man ive just tested the settings you gave me and gues what............it didnt work so far:)

ive got som e questions tho.

FSB Overvoltage Control can it also be +0.10......didnt had +0.1?
(G) MCH Overvoltage Control can it also be 0.100 didnt had +0.1

And the cpu voltage how much do you think i should increase? i tryed 1.40000
Should HPET Support be on (Enabled)

And most important question, the memory mullti....should it be A,B,C,D?

And do you know of something special i should think of on the next try...........this time 2 quick reboots and stock like before.
But its fun to try, thanks for your time mate:)

**Lsdmeasap** · 09-18-2008, 07:03 AM

Re: X48T-DQ6 issues with TW3X4G1800C8DF

Yes, overclocking is not a Plug and Play thing, you may spend many hours tweaking things.

Yes +0.1 is the same as +0.10, and +0.100, and +0.10000 and so on. It is still all .1
Q6600 can take up to 1.5+. I would think 1.45 or below would be good. Watch your temps is all.

HPET disabled for now if you like.

Memory mutli, it will show you on the right side of the BIOS screen which letter corresponds to what strap, you want 333 or 400 strap

Re: X48T-DQ6 issues with TW3X4G1800C8DF

Im sorry man ive tryed and tryed and nothing will keep:(

I give up this is nothing for a common person that not understand, my memories have to go at 1066...........not 1800 (thats very sad)

Ive tryed change the volt on the cpu to almost everything between 1.32500v up to 1.4 like you said.......just rebooting.........on the memory i tryed the lowest and the highest settings you rekommended, rebooting.

Even tryed 1N-2N......same same.............tryed high fsb, and low fsb same same.......

This cant be done:(.....................again thanks for your help, atleast the computer works at stock, but its sad..............

regreting buying thoose memoryes now

See ya!
Wondering if E8500 will be oki processor, atleast everything will be going at 1333, and the memory will follow????? maybe.............

**Lsdmeasap** · 09-18-2008, 11:27 PM

Re: X48T-DQ6 issues with TW3X4G1800C8DF

You may need more then 1.4 for sure. What speed CPU was you trying? You may even need 1.5 set in the BIOS, all depends on your chip, and what speed you are trying at the time

RMA the ram for better brand, and slower speeds if you do not like it. I would not keep it if I did not like it

1333 FSB CPU will only run at 333 FSB, which you are already past so that would not help at all, and is not your issue. You likely need more volts

Please post what is failing that you are trying
