Asus p5q premium 8gb ram freezing gskill 8500 model

[Edwired]

Oh i can understand totally as far as i know the fsb:dram = 5:6 which should relax the ram abit than a tight 1:1 ratio which require tight timing and low speed. What i trying to find out is that should i bump up the northbridge to make the computer abit more stable. But i did see the g-skill page about the voltage between 2.00/2.10v to run at 1066mhz tested on 5-5-5-15 timing

 

[agent_x007]

You must up NB Voltage to make DDR2 1066MHz 8GB stable on LGA775.
I'm guessing ~1,35V in your case should be enough.

Thinking about FSB: DRAM ratios is pointless on ASUS boards, since they have 100% control of NB Straps (Strap option in BIOS) and memory Performance Level (AI Transaction Booster).
You can make work any FSB/DRAM ratio with those options (and high enough NB Voltage).
High FSB (500MHz+) is bigger problem for Quad Core CPUs than FSB/DRAM ratio.

Oh, and "1:1 ratio" you keep mentioning, in Your case means 533MHz on FSB [effective 2133MHz] and 533MHz [1066MHz effective] on memory.
Minimum real DRAM speed (real = 1/2 effective), must be equall to real FSB frequency.

PS. For system stability, higher Performance Level is better.

 

[Edwired]

The northbridge goes in 0.02v steps. And the fsb straps it on 333 should i leave that in manual or auto. As the performance booster should that be higher than 10 for more stability than performance?

 

[agent_x007]

So set 1,36V on NB Voltage, with P5Q Deluxe heatsink it really shouldn't matter.
FSB Strap of 333MHz is fine, however if you want more DRAM frequency options, use Auto setting.
Higher Transaction booter = More stability and less performance.
Low transaction booster = Less stability and more performance.
Transaction booster setting = forced Performance level.
There is however a point when going too high on it will destroy performance and still not make things stable (examples : Bad timing settings/too low NB voltage/too high DRAM[FSB] frequency/too low FSB voltage/bad GTL setting/all before mentioned options or their combinations).

PS. Let the board/BIOS handle 2-nd and 3-rd level timings (aside from Command Rate - set it to 2N and don't change).
Focus instead on AI Transaction booster, NB Strap and Voltages.

 

[Edwired]

Yeah that could be the reason why im getting the freezing due to the transaction booster set too low may bump it up to about 15 to gain more stability. As the heatsink on the northbridge is modded as i cut the pipes off it and stripped off the asus logo plate to get more air through the fins by a 40mm fan and the bios fan profile to standard as i have no control over the 40mm fan if set to disabled it sounds like a jet with the fan viberating through out the pc case, may to find double sided tape with foam to reduce viberating. Yea i try that setting tonight. And i report back sometime tomorrow with result

...seriously ?
You know there is that optional ASUS fan that fits on VRM heatsink and can be controlled via BIOS... right ?

Example : LINK
Why hack the board when heatpipes and optional fan can take care of excesive heat for you ?

 

[Edwired]

As i have no room to fit the asus fan as i have 140mm fan noctua c12p se14 heatsink. As here the link showing that it covering the vrm heatsink as it blowing air down

[agent_x007]

You don't need additional fans on VRM, when CPU cooling is blowing air straight down on PCB (ie. like BOX cooler).
Basicly : Adding more fans to VRM with the type of cooler you have won't make any difference.
If you want VRM/Chipset to be cooler, add case fan that will pump cool air from outside to inside (preferably on CPU fan or near it).

 

[Edwired]

As i have 200mm fan in front of the nzxt phantom 530 case blowing air in with 140mm on the back exhausting as well 2x 120mm on top exhausting. And modded xbox 360 fan blowing air on 4 dimms and 40mm fan on northbridge as the northbridge does get abit too hot for my liking

Did abit more testing with the northbridge at 1.36v and the transaction booster at 15 and the ram at 2.20v (dmm reading between 2.14v to 2.17v depends on ram load) got further in the valley benchtest software started to error out about 8 mins in with error 1000 in the event viewer which point out the 1st sub timing needs tweaking as it 5-6-6-18-4-8-4 at the moment

 

[agent_x007]

5-6-6-18-4-8-4 Names for last three timings ?
Try using "Auto" setting on them.

 

[Edwired]

My bad it 5-6-6-18-4-55-8-4 set manual. On auto stated 5-5-5-15-3-55-6-3.
My question im trying to run at 4.0ghz 444 fsb with the ram speed at 1067mhz. Which way do i tweak the ram timing like more or less as im about 80% getting the idea of voltages and fsb and the other settings. The other 20% is where my head is lost about the ram timing related kidmijig

 

[basco]

just for info:
quick ram timings changing in windows with cpu tweaker 2.0 or memset v4.1:
http://www.tweakers.fr/download/CPU-Tweaker.zip

1 of the more important timings is perfomance level- try raising it after test fails.


on my p5q-e the northbridge would be cooking with 1,54volt on air!

and here is someone with nearly the same prob-maybe ya find something in there:
https://forums.tweaktown.com/asus/62917-asus-p5q-xeon-x5450-overclocking-2.html

another one:
is this a kit of 4x2gb sticks or a 2x2 kit x2- maybe you have different chips under the hood? look at the sticker with serial number and look if they differ: ex: 49100640..... means 49 week of 2010 with elpida chips

Keep timings as they are (only force first four to 5.5.5.15 and Command Rate to "2").
Tweak Voltages, and Strap/Performance level. NB GTL might be a good idea to look at.

 

[Edwired]

Well the ram timing are 5-5-5-15-4-85-8-4. Northbridge is 1.40v. Will further tweak the gtl settings another time. As im getting further into valley benchtest was getting crashing and abit of system freeze.

Update = The cpu is clocked at 3.61ghz, fsb 450, ram 1080mhz, with the above ram timing along with the voltages cpu @ 1.304v, gtl 0/2 and 1/3 = auto, fsb term @ 1.28v, northbridge @ 1.40v, nb gtl = auto, southbridge @ 1.30v, sata @ 1.50v. The ai transaction booster is 15. Fsb strap @ 333 No freezing at the moment

Please Read Dram frequency, set it from auto to manual, back it off from DDR2 1066 to DDR3 835 first, then after that try DDR2 887. Basically what is happening is since the CPU FSB is set from 333MHz to 444MHz, which is a 111MHz Boost or effectively a 1776 FSB, and your ram is set to 1066 which is really 533MHz, you are increasing from 533MHZ (DDR2 1066) to 644MHz which is DDR2 1288, so the Ram OC is way out of standard, timings at 1066 are too tight for your OC. You need to loosen the first 4 values by 4 or 5, then adjust from there.

Example DDR 2 887+ 111MHz= 998. You are still in Range of what the 1066 Ram can handle with the timings for 1066, you can even tighten them slightly.

If ram is set to DDR2 1002+ 111= 1113, which is out of DDR2 1066 spec, you need loosen timings.

So basically you really need to run your ram at DDR2 887 with timings of 1066, or loosen timings up a bit if you select DDR2 1002.

One more thing, if you attempt to try the ram at your 1066 Profile which becomes 1288, you will need to go to gskill and compare your timings of your 1066 ram and ddr 3 1333 and find a good middle ground, if it will even take. Otherwise if at ddr 2 1002 which is 1113 they will be in between 1066 and 1333 and might be able to be obtained.

According to cpuid and hwinfo the ram is running at 540mhz just a mild bump in overclock as im not putting the ram out of spec as the strap is manually set to 333 not 400 or auto. If i leave the strap auto it will try the fsb/dram to 1:1 ratio and the first dram freq selected then all hell breaks loose in the operating system. As the above post im not getting any lock up at the moment.

Okay try to see if you can up the multiplier of the processor to 9 since it sounds like you are running it at 8 right now and 9 is a maximum that Xeon will run

 

[Edwired]

Yea i had to put the multi to 8 to see where the problem is popping up else where. As the valley benchtest is still going at this moment, the temperature reading on the cpu cores are hoovering around the 46/49c which tells me i still have abit of headroom for multi 9 which brings it up to about 4.1ghz

450x9= 4050, 455x9=4095, 456x9= 4104.

I try that out tomorrow evening to see how it respond

Well everyone just didtnt get a chance to do the settings as requeated and testing as im due for an operation on cataract surgery as i be banged up for a few weeks but will keep you inform as soon as possible

Hey everyone i just got the newer e5450 cpu in the post today. Had to put the vcore in the bios to auto to see what vcore the cpu is getting as it shows 1.192v in cpuid and when playing dirt 4 it shows 1.200v. As the cpu vid shows 1.113v in hwinfo64 compare to the other e5450 it shows 1.163v. As the old e5450 @ 4ghz, the vcore would be hitting 1.232v idle and loaded 1.240v in vcore set to auto but runs abit hotter and consumes more than 83 watt. And the newer e5450 is consuming less power about 65 watt during dirt 4 @ 4ghz. The temperatures are alot cooler with the newer e5450 about 5c to 7c differences compared to the older e5450.

Different stepping i presume

No same but different vid. Decided to drop the dram freq from 1064mhz to 889mhz with fsb:dram ratio 1:1 was able to play battlefield 3 alot longer as it more demanding on cpu but getting appication error 1000 in event viewer which could point to ram timing being abit tight. As im running memtest to see if it popping up errors yet. With the timing in auto it showing in bios 5-5-5-15-3-52-6-3. Was thinking of loosing up to 5-6-6-16-4-55-7-4. What you think?
