SPDTool: Read, Edit and Flash your Memory's SPD

And... how can I do that?
It says the supported CAS Latencies is 3, but it's CL is 2.5!
How can I set it to 3?
 
I tried submitting a couple of SPD dumps from a couple of el-cheapo low-end PNY Optima sticks and it pops up with this when I hit 'submit'

not sure if that's an error or not . . .

anyhow, if you didn't get those SPDs, I've got the dumps saved if you'd like to add them to the database, just let me know.
 
Is there a way to tell if the memory is connected to the SMBUS properly for SPDTool to work?

I have tried 0.62 on a system (SuperMicro X7DAL-E with 4x1GB FB-DIMM's) and SPDTool says the memory is not connected to the SMBUS (it must be connected somehow for the SPD to be read though, right?)

Any info would be greatly appreciated, trying to push the system and the FB-DIMM's stop dead at about 400mhz without dryice on them ;)
 
Hi, guys...
I want to change SPD timings for 667Mhz from 5-5-5-15 to 4-4-4-12. The memory is Cellshock 667 D9GMH.
The problem is that I don't understand how the ns are related to timings and what should I change to have TCL, TRCD, TRP = 4 and TRAS =12.

Are we able to change the spd Vdimm?
i`ve got 1.8V and i want 2.0V.
 
I want to change spd on my laptop, deafolt is 2T and i want 1T and 2,5 3 3 7 it is long work to set it over and over agin in windows
 
I have some OCZ Platinum Rev.2 DDR800 stick. When I "read" the memory with SPDTool, the CAS, TRCD, TRP, TRAS, TWR, TRC settings in the EPP Profiles are all "Undefined". Can I still change them?
Also, will changing the Profile Voltage Level actually tell the motherboard to boot at a higher memory voltage? Since my motherboard doesn't have memory voltage adjustment
 
I have no clue whatsoever how to use this tool :confused: , but I would like to know if there is anything I need to change. I intend to OC my system this week,and thought that "perhaps" doing some adjustment to memory should maybe be done aswell.

In my BIOS I can set the voltage up to 2.8 btw, and the actual speed is 200Mhz (the modules support 400Mhz), other than that it is 3-3-3-8. On another forum, one guy said I do not need to "touch" the memory if I intend to clock in small values, but I don't know how far I can OC the cpu.. Maybe later today I'll get a better hs/fan for the system instead of the stock bs/crap that is on right now. I managed to get from a friend a 120mm fan for cpu's since he went into the "water business".


Thankful for any replies given.
 
No uploads anymore?
 
So how do the timings translate to nanoseconds? Is there a formula or what?
I'm going to get his sticks after work today and program to these timings on my Maximus Formula in Vista x64 Wish me luck. :p
 
Waiting impatiently for new version with DDR3 support. Also would be nice to include XMP/EPP2.0.
 
Upload SPD via SPDTool dont works...

Here is my SPD from

Corsair Dominator CM3X1024-1800C7D v3.1 (CM3X1024-1800C7D) Orginal Dump

Corsair XMS3 CM3X1024-1800C7DHX "XMP version" (CM3X1024-1800C7DHX)
This SPD is same as CM3X1024-1800C7D but added XMP Profile

Data from the SPD i found here:
http://www.ixbt.com/mainboard/memdb-corsair-ddr3-1800c7d.shtml


XMP=Intel Extreme Memory Profiles

Pc133-333

Sure wish there were some sort of manual

I have some PC133-333 SDRAM that runs unstably as PC100-222 in a Mac; I want to under-clock it at PC100 speeds

Anyone any guidance on what I should be altering and what I should be aiming for, PC100-322? and how

Hi simri,
My situation is also a bit weird. I have a pair of CM3X1024-1800C7D v3.1.

The factory programmed SPD of one module reads on CPU-Z as to be CM3X1024-1800C7DHX (I do not know if it was supposed to be 1800C7D; I mean non XMP).

The most weird thing is, other module appears to be a CM3X2048-1333C9DHX according to CPU-Z SPD readings. (although it is a 1gb stick). The maximum SPD programmed frequency of this modul reads to be 667. It reads the same thing regardless of switching RAM between DIMM slots.

I browsed web and heard of a utility called Thaiphoon Burner downloadable at http://cbid.amdclub.ru/

This utility supports also DDR3 memory, however you can not edit certain memory timings of a DDR3 on its SPD using this utility since it has a limited supported as of yet.

You say "upload SPD via SPDTool dont works", do you mean you can not flash your SPD after editing parameters by using SPDTool?

If this is the case, Thaiphoon can also import SPD profiles derived by using another software like SPDTool. If you can edit all parameters of a DDR3 SPD by using SPDtool, which Thaiphoon is not capable to do all, you import this to Thaiphoon and flash your memory.

Check the SPD with Lavalys EVEREST Ultimate Edition 2007 v4.50.1330
 
Here is a bug in all versions of spd-tool with DDR 1 memory.

The number of dimm ranks are false. spd-tool reports 3 ranks, but the module have 2 ranks. A 1 rank module is reporting as a 2 ranks module.

Thaiphoon Burner reads the SPD correct. I hope you fix this bug soon. :)
 
SPDTool writes wrong values

Hi All,

I am trying to set the trfc values on my 4x1 GB kit. Default is 105ns (69), and I want to change it to 127ns(7f).

However when I use spdtool to change the values using the drop down list, it almost always sets it to some high value ( > 300 ns) when I write them.

Am I doing something wrong? Using version 0.62 on Vista.
 
Hi, I have a question. I have a Kingston Value Module of 1Gb, I want to add an EPP profile to it's SPD. The thing is that I am not shure is that possible on a Value module?

Sigh... This is just wrong! LOL I have a M3N-HT Deluxe MB and Crucial Ballistix PC6400 RAM and it says ...

No Memory Modules Found. Incompatible SMBus driver?

My memory runs great as 1066, but if I try to increase me FSB for the CPU it will not post unless it is set back down to 800. I was thinking this might be a great work around. Especially as I have two sticks I dont use to play with! LOL

Help? If the answer was within the many pages of posts I missed it in skimming through.

OOPS! Editing in that I am running XP Pro X64 if this matters!
 
SPDTool can not write SPD on Spectek memory

I've used with success SPDTool on my system and edited the SPD data on my ram modules, but I'm not able to write SPD on Spectek DDR266 128MB memory. Spectek SPD seems to be unwritable. My motherboard is a Gigabyte ga-7vrx rev 1.1 with via kt333 chipset and it is supported by SPDTool.
Why Spectek SPD is not writable?
 
Any chance of a little update please W1zzard?

I can't read or write on an Asus P5Q3 Deluxe
"No memory modules found. Incompatible SMBus driver?"

If there's anything I can do, I'd be happy to help *shrug*

SpdTool needs updating. Doesn't support ICH10R.
