Memory Issues

[kimsland]

Damn!

Yes I believe it is the PowerSupply

About 95% agree !!!

Please purchase (or borrow) another PowerSupply that has the full 24pin plug and 4pin CPU plug, and Sata power too.

 

[andy06shake]

the PSU is 24pin the connection im refering to is the ATX12v located 5cm in on the upper left hand corner of the board(in between the heat pipes/sinks. And the 4pin conection that goes into the 8 pin conecter leaving 4 pins unused on the left of the 8pin conector does indeed supply 12v. I agree it could be that the power, but could this really disable or only supply power for 2 of the sims. I have never had any power issues.

 

[andy06shake]

I mean you would think that if there was any power issue Nvidia Sentinal would repot it considering that my GFX card is the most power hungry component of my rig(Asus EN9600GT)

 

[kimsland]

Hangon, which power pins again, I've just gone blank

Maybe post a pic from the web somewhere (too busy to look it up right now)

 

[andy06shake]

This is the power conector that has the 4pin 12v conectror inserterd leaving 4 pins open on the left but still supplys 12v

 

[kimsland]

Why wasn't I informed of this new update to motherboards? (um this is a stupid retorical question, don't answer)

Well the 4 Pin is power to the CPU
What's the 4 for? I'll have to check it out (and update myself, probably came out years ago no doubt!)

Meanwhile, please find another 24 Pin + 4 pin Power Supply (I still think it's this even though.)

That should be fine the way it is in terms of the connectors but what brand is your PSU? Sounds like a Trust PSU to me.

Have you checked that you have the memory voltages set correctly in the BIOS.

 

[andy06shake]

This is where i really dont know what to do. How will this some how enable me to insert the other 2 1gb sims If i cant get the bios to post with 4 sims inserted? What do i change the memory voltages to? Can i blow my board/memory if i set it to high or incorectly? What is CAS latency and memory timings? As to my PSU i blew one recently and had to get this £40 piece of crap, yes its made by Trust. I include my CPU-Z data incase that can help.

 

[nickc]

when u bought the memory it should have been stated. if the mem came with any instructions it should be on that paper.

 

[andy06shake]

The RAM came in a sealed plastic cases, yes there is a pamphlet but the only instructions on this are pictorial and on how to insert/remove the RAM.

 

[andy06shake]

Ok i have had a call from someone from Kingston Technology, This chap seems to think that its the onboard chipset of the memory that my board has a problem with(KTC 99U5316-010.A00LF). So i think that i will return it to them and hope that the new memory sims work this time. Can anyone tell me more about how the onboard chipset of the memory sims is relavent to this problem. I thought DDR2 memory was compatable with all DDR2 boards?

 

[kimsland]

No they're not !

I've had exact same specs as stated by what the board can take, and the Ram just will not work
This is where the Manufacture of the Motherboard, state which Ram has been fully tested in their Motherboard.

Why is this so?

There's also a unique code in the Ram, to identify it to other hardware (just as all hardware has) I believe that this static address area has been expanded over the years, with more and more information added to it. Thus causing conflict

But I really don't know??

Just that, not all Ram suit all computers (even with same spec and voltage rating)

 

[VBAssassin]

Lol, this topics gone all over the place. From being the power supply, to updates, to being the memory lol.

 

[kimsland]

It is difficult at times to find the answer

Especially when the fault is in the Programming of the Brand New Working Ram
I'd say it should be recall on them myself

Apparently, the 'fix' is to run the 4 modules at 677 Mhz with 4-4-4-15 timing.

ref: http://72.14.205.104/search?q=cache...SLI+4+Gb+ram+problem&hl=en&ct=clnk&cd=3&gl=ca

 

[kimsland]

So since 2007, all users must downgrade their ram, under this condition to 677 Mhz ? That's a bit sad.

 

[CCT]

Well, realistically, with XP you can run a 512 Vid card and 2048 in fast RAM and create a 2048 min/max page file and get good response.

So, really, the issue is 'Why install 4 Gb in XP?'.

 

[andy06shake]

What i would like to know is why my older Asus M2N8-VMX board supports Different size and frequency, i have 2 512Mb 667Mhz and 2 1Gb 533Mhz of DDR2 installed and its working just fine. But a newish board like my Asus P5N32-E SLI requires 2 sets of matching pairs?

 

[kimsland]

Because everything these days are released before extensive testing (including MS Operating Systems ! )
We are the guinee pigs

 

[nickc]

good one kimsland, and I agree!!!!!!!!

 

[andy06shake]

Thats some sick tec. So why are ASUS allowed to state said board(ASUS P5N32-E SLI) supports 8Gb when u cant get it to see more than 2 1Gb sims. Whats the deal are u supposed to use 2 4Gb sims(Do thes exist yet as DDR2 memory?) in only 2 of the DDR2 Ports?

 

[CCT]

This is one of those cases where reading the manual (page 2.16) helps to clear the air.

They state what 5 specific OS's will support 8 Gb of Ram. 4 are servers and XP Pro X64 is the other.

Vista is NOT on that list, either in 32 or 64 bit.

Further; http://support.asus.com/faq/faq.asp...80A5F749E54&model=P5N32-E SLI&SLanguage=en-us

At the Asus site, they identify what older mobo's will support installing Vista. The deluxe versions of the ASUS P5N32-E SLI will apparently handle it.

[andy06shake]

I know that a 64bit OS is required but the issue is getting the board to post the bios, thus allowing me to install Vista Ultimate 64. It dont matter what OS u use! No bios, no OS simple as!

'I know that a 64bit OS is required but the issue is getting the board to post the bios, thus allowing me to install Vista Ultimate 64. It dont matter what OS u use! No bios, no OS simple as!'

Makes no sense - use 2 sticks and get into Bios.

 

[andy06shake]

So if i go back to 2Gb system, install Vista Ultimate 64. Then insert the other 2 sims ur saying the board will miraculously see this other 2Gb? When it wont post the bios currently with all 4 sims inplace.
