You mean like these cheapo DDR-400 modules below that run at 312MHz on my desktop???
(4992MHz for my watercooled P4-641 )

Had to up the voltage "a bit" and attach heatsinks to obtain these insane speeds, but hey...
SPD Tool did it, cheap or not

So, I'll rephrase my question.

Has anybody had success in tweaking 1GB SODIMM's (not DIMM's) with SPDTool?


El cheapo DIMM's:
[ DIMM1: Swissbit SDU03264B5B71MT-50 ]

Memory Module Properties:
Module Name Swissbit SDU03264B5B71MT-50
Serial Number 4E0C0000h (3150)
Module Size 256 MB (1 rank, 4 banks)
Module Type Unbuffered
Memory Type DDR SDRAM
Memory Speed PC5000 (312 MHz)
Module Width 64 bit
Module Voltage SSTL 3.3
Error Detection Method None
Refresh Rate Normal (15.625 us), Self-Refresh

Memory Timings:
@ 333 MHz 4.0-4-4-11 (CL-RCD-RP-RAS) / 19-24-4 (RC-RFC-RRD)
@ 232 MHz 3.5-3-3-8 (CL-RCD-RP-RAS) / 13-17-3 (RC-RFC-RRD)
@ 200 MHz 3.0-3-3-7 (CL-RCD-RP-RAS) / 11-14-2


[ DIMM2: ProMos/Mosel Vitelic (256 MB PC5000 DDR SDRAM) ]

Memory Module Properties:

Suggestion: Any chance of being able to maximise spdtool to a full window w1z? I'm sure I'm not the only one who would find spdtool much easier to work with in a full window

[Manuel]

Something fishy?

Tried 3 brands of 1GB DDR SODIMM's: PROMOS/Vitelic, Hynix and Infineon: no go

Tried 4 brands of 512MB DDR SODIMM's: PROMOS/Vitelic, Hynix, Infineon and Elpida: success

Anyone?

new version 0.62:
Digital Signature added to improve support for 64-bit Operating Systems

[Ketxxx]

"the current dump does not have a valid checksum" spdtool 0.61 spews that at me after i changed some spd timings and went to overwrite the original data on my xp8000, anyone else got that? knowing how invalid checksums can really fark stuff up I'm not gonna do anything till thers a lil more info available.

[Ketxxx]

ignore above post, I went and flashed anyway. Didn't help me. Looks like it may be a CPU or chipset limit after all.

[Klimpen]

This is a nice app if it weren't for the fact that it scares me a bit.
I have a pair of OCZ PC2-9200 FlexXLC Edition 2x1GB Micron D9GMH and they refuse to boot on my Gigabyte P35-DQ6 after a CCMOS. I kinda "know" the reason, they LOVE to have more then default 1.8V to boot.
Because after inserting another el'cheapo stick I can boot and up the volt a bit.
I can then boot with the OCZ and everything is fine.

Can you guys tell me if and how I can use SPDTool to correct this. I see I can choose from 1.8 or 2.5 Volt in SPDTool but 2.5 is a bit high even if I can have that for a short while.
But is there any other way to set the SPD voltage to lets say 2.2V or actually the rated volt for my mem's that are 2.35V

[zdanovych]

It seems that there is no DDR3 support yet Is it in schedule?

[inteks]

hiho,

really nize tool! maybe this is what i need, but i dont know for shure what to do.

i underclocked my mediaplayer. the cpu is a 800mhz cpu but i run it at 533mhz. (for near passiv cooling )

the problem is i cant select the ratio for this mobo

what should i change that the mobo thinks its ddr400 and set it to 1:1 @ 333mhz / 2-3-3-6 automaticlly ???

thx ia
inteks

[inteks]

thx thx thx this tool rock

i set the sdram cycletime to 5.00ns (200mhz) and leave everthing else untouched
and voila ->>>

[psyko12]

^ As noted from above he had 5:4 divider, I get that too from my mobo, and don't set RAM to 1:1 if the proc was p4, however when upgraded cpu core 2, bios unlocks ratio, can this tool fool my mobo to run dual channel, got bad pair of rams 1 double sided and 1 single sided.... Thoughts please... Thanks

Hi guys is there a tutorial on how to use this?

I have a 266hz single 1gb stick I'm trying to get working in a brand new P5K
The stick has "d9gct" on it and is apparently a "Micron D9" meant to be quite good according to
http://www.jmax-hardware.com/index.p...1&limitstart=1 (french)

It will NOT post in my P5K board at all.
I've been informed on numerous forums that 266mhz ram simply doesn't work on the P5K??

I'd like to flash the ram to 333mhz, loose timings, doesn't even bother me - I just wanna use this ram (temporarily) until my OCZ DDR2-800 arrives in Aus from the USA.

Anyone know precisely what I need to change to acheive this?
I'd really appreciate it and I'm not a total noob but my inital changes I've made on the stick are NOT reflected in CPUID, so I'd assume it's not working?

P.S I appreciate your time, thanks guys.
P.P.S I have a spare machine to do this on which does recognise the ram and boot.

I'm getting the no memory modules found, incompatible smbus driver - it's under Vista.

Is there any chipset driver I can install to fix this or am I SOL?
I need to flash some chips

It's an intel 845 chipset I'm trying to do it on.

[infrared]

Yeah, the board won't post with pc2-4200 modules in it.

Try flashing one to this spd, and see if it posts: http://www.techpowerup.com/spddb/details.php?id=18

your modules should be able to handle 333mhz without probs.

Thanks for the response but the machine I'm trying to flash in is having SPD issues
I might have to flash them at work! damnit.

Is there anything I can do to make this 845 board 'flashable'? It has Vista Ultimate on it at the moment, I can switch to XP would that make a diff?

[scottylans]

Make that a 945 chipset.

[scottylans]

I tried to use this tool and it didn't work, I don't know what I did wrong.
I want to make my 266mhz ram boot at 333mhz, I know it can do it. (It's Micron D9)

1gb single stick "d9gct" it's rated to 266mhz by HP but in actual fact several web sites claim it'll do 500mhz.

All I want is 667 so I can boot my PC tonight and use it before my 'real' ram comes from the USA :/

I've changed 3 settings as per this post
http://forums.whirlpool.net.au/forum...806194&p=2#r38

First setting I changed

Second setting I changed

Third setting I changed

Timings
http://img212.imageshack.us/my.php?image=timingwk9.jpg

Basically I just want this stick to post on a P5K, I don't care how slow the timings are!
Do those settings look like a 333mhz (667) stick or a 266mhz (533) stick?

[scottylans]

Got it all working, thanks all

I have some Kingston DDR2 for a D620 that is rate at PC3200. It is currently running at 200MHz, 5:6, 3-3-8-11. I'd like to bump it upa bit to say 267MHz or 333MHz (and loosen the timings accordingly). It would see that this memory shouldn't have a problem. I can run it a 3-3-6-11 with memset so it would see an increase in the Freq should be ok. so my question is 1. what settings do I adjust to get it run at 267 or 333 with say 5-5-15 timings? All the ns stuff has me confused. (also should I bother since it is running at 3-3-8-11). It is KTD-INSP6000/1G with part D6408TEBGWL3U. ANy advice would help!

I was googling default volts for cpu and my memory, knew them both but was making sure, and i came upon your post here man.

Wtf u been up to freak?

Hi,
I have bought few DDR2 800/1GB modules recently. My idea was to overclock them, but there is a problem hire - unfortunately none of them can reach 850Mhz (ddr2). I did some research on Internet and have found some interesting facts. For instance PQI 1GB DDR2-800 with PQD2648E25R chips can hit 800MHz at 3-4-3-12 @2.1V and 1066MHz - 5-5-5-15 @2.1V. The same DIMMs but with PQD2648P25R chips hit their limit at 860MHz on CL5. Both use expensive PCBs - Brain Power BP ML E186014 94V.
So I want to give another chance to my DIMMs before throwing them away. I intend to flash them with SPD from upper class modules produced by the same manufacturer. First pairs are 2 x PQI DDR2/800-1GB and 2 x SuperTalent DDR2/800-1GB.
Some help with finding SPD from PQI DDR2/800 Turbo 1GB and SuperT DDR2-800C4 1GB will be appreciated.

[acer4ever]

Hey!
SPDTool reads all data from my RAM just fine. (2x1gb Geil Ultra / Asus P5N-E SLI 650i)

is it possible to change the COMMAND RATE ? CPU-Z 1.41 shows no info in the Command Rate field.
For some reason my GEIL gx22gb6400udc with Aeneon chips boots at 1T when it is not supported by these modules @ 800Mhz

Changing it from BIOS solves the problem, but I can't run this memory in boards without that setting option in BIOS.

thanks!

[Brother Esau]

@W1zzard......where is the data base address and is there a help file yet mate?

[andrebrait]

is it safe to change CL from 2.5 to 3.0?
Yes, I'm increasing it, coz I have an AMD64 bug with this latency...
