Ok I just put in 2 new sticks of this 2gb memory for my computer:

http://www.newegg.com/Product/Product.asp?Item=N82E16820141227

But when I installed it when I first booted up my computer on the bootscreen it gave me this message:

"Serial Presence Detect device data missing or inconclusive. Properly programmed SPD decive is required for reliable operation. DDR 333 mhz memory assumed at slowest timings."

What does it mean?? I just took out my old RAM and installed this and now it gives me this message. I have 4 open RAM slots with 2gb maximum on the MOBO but I only use two since its channel and the thing still gives me this message, what do I do?

I just want to set my RAM at 400MHZ and set the timings at 3-4-4-8. I dont care about overclocking or any of that...just yet :p How can I access the BIOS screen to manually set it if my computer won't do it for me?

Heres a few of my system specs...if it helps...and i blanked out all sensitive data -_-

A short, practical primer: modern DIMMs carry a small EEPROM called the SPD that the firmware reads during POST to learn a module’s voltage, timings and speed so it can configure the memory controller automatically. When the firmware can’t read or trust that SPD data it will fall back to very conservative defaults — that explains why the machine still boots but runs at slower timings or lower frequency. Kingston SPD glossary. (kingston.com) Dell knowledge article on SPD boot messages. (dell.com)

Straightforward troubleshooting sequence (work top-to-bottom and mark what changes): test each stick alone in the primary slot to find a bad module; try the same stick in each slot to detect a bad socket; swap paired sticks into the manufacturer’s recommended paired slots (as suggested); reseat modules and clear the CMOS to restore defaults. If you can enter setup (as explained and confirmed), load defaults, then look for manual memory or chipset timing options and try the module vendor’s published settings. Check the OEM upgrade notes or service manual for any slot/pairing rules before mixing modules. Sony RAM/upgrade guidance and manuals. (sony.com)

If a single stick fails or the SPD still won’t read: update the BIOS (OEM/Intel updates sometimes improve SPD/compatibility), and check the board’s tested-memory list or QVL. If the module’s SPD EEPROM is corrupted, vendors or specialists can reprogram SPD data (tools exist), but that is risky for end-users — RMA or replacement from the memory vendor is usually the safe route. Examples of SPD tools and vendor utilities are documented by vendors and community projects. (guru3d.com)

Recommended order to resolve: single-stick tests → reseat/clear CMOS → try manual BIOS settings → BIOS update → contact Sony or the memory vendor for RMA/support (as suggested). Avoid mixing different module types (registered vs. unbuffered, ECC vs. non‑ECC) and stop once you see instability; hardware replacement is safer than forcing unreadable SPD data. (crucial.com)

Of the top of my head, I would put the two modules side by side. J6G1/2

Can I have more specific help please? Changing the RAM slots around doesnt help. I just want to access the BIOS and set the settings manually there, but I dont know how...

BIOS setup pages are accessed by pressing a certain key (or keys) just as the computer starts to boot up. The exact key varies between BIOS makes/versions, but some common keys are F1, F2, Del, and Esc.

Look at your startup screen just after you power on the computer; you may see a message which says: "Hit F1 to enter setup" or something similar. If your BIOS/boot messages are hidden by a startup logo, try hitting Esc to bypass the logo and view the BIOS screen.

OK I can access it by pressing F2 on the boot screen. Now, I don't want the RAM's MHZ and timings set by the computer, since it says they are at the slowest possible. I want to manually set it, how can I do that?

I want it set at 3-4-4-8 and at 400MHZ.

I'll have to look further into the specifics of your mobo and RAM sticks tomorrow, but I'll bet the RAM modules you have are not entirely/fully compatible with the mobo, hence the SPD error.

The PQI RAM I got is pc3200, 184 PINN, DDR RAM. Which was what my last set of 256x2 RAM was...

I mean, its still showing in my 'system' menu on the control panel that I have 2gb of RAM, so its compatible, but I guess the computer itself is just setting the MHZ and timings the lowest they can go?

Doesnt ANYBODY know whats wrong with my RAM? :sad:

Member Avatar for Dortz

i couldn't find your board anywhere on the intel site, much less find a list of compatible memory sticks for you. i looked around on the pqi site, and they sound prettty proud of thier products. i suggest e-mails to both companies, explaining your problem, and go from there. It sounds like an incompatiblity issue to me, but there's no proving that without one of the two saying a definite yes or no.
