any suggestions??

Δημοσ.

Παλιά υπήρχε ασυμβατότητα μεταξύ geil και nforce2, αλλά εδώ και μήνες το πρόβλημα έχει λυθεί, Μήπως έχεις πέσει σε παλιό stick?

to stick agorastike mesa fevrouariou.. les na me doulepsan sto hac(an kai den to pistevo)?? to mono pou mou eipan einai oti to nforce2 den ypostirizei ddr400 alla mexri ddr333 alla me "ligi piesi" mou eipan pos den tha exo prob...

TI SIMAINOUN TA TIMINGS!!!!!

variomoun na to metafraso:

Memory timings

Memory timings

Why is it important to have paired modules? In a word, timings. Every memory module has a speed rating and this rating dictates how it will be used by the memory controller on your motherboard.

 

Some of you may be a little confused as to what all of the numbers mean when you buy a piece of ram. The general rule of thumb is this: "lower timings + higher speed = good".

Though does it always matter? For everyday usage like web surfing and general 2d office apps, you won't notice any difference. Low timings really come into play while running memory intensive application like games, graphics and program development. In these cases the faster the better.

 

Memory Timing Terms

CAS Latency: is a number that refers to the rounded ratio between column access time and the clock cycle time. A CAS Latency of 2 @ 200Mhz would look like this

 

CAS 2 = 10ns (column access time) / 5ns (clock cycle time @ 200Mhz)

 

Clock Cycle Times

5ns = 200Mhz

6ns = 166Mhz

7.5ns = 133Mhz

10ns = 100Mhz

 

The relative constant in the equation is Column Access Time. This number will have an effect on the CAS number as the Clock Cycle Time changes.

 

T(RAS) Active to Precharge: T(RAS) specifies the amount of time required between an active command to a precharge command. Basically this means the number of cycles that must pass after a bank is opened to when it can be closed. Lower is better.

 

T(RCD) Active to CMD: T(RCD) Is the time we have to wait between a row access request and a column access request. Also can be called RAS-to-CAS, this number should be the same as your CAS Latency number for the best speed.

 

T(RP) Precharge to Active: The amount of time from a bank precharge request to when it can be activated.

 

One thing to keep in mind is that these timings are all related to one another and are controlled by the Clock Cycle Time. As the Clock Cycle Time decreases the timings will increase to compensate.

 

Back to memory timings, the memory modules can only be as fast as the slowest link. This means when you mix CAS2 modules with CAS3 modules or even dissimilar CAS2 modules the timings will be adjusted to the lowest speed of each module. The result will become the overall SPD rating for the combined memory modules in the subsystem. These failsafe measures will usually result in very low memory scores but can cause stability problems as the Clock Access Time increases. (aka when you overclock)

Εγώ γιατί νομίζω από την άλλη οτι ήταν/είναι γενικό πρόβλημα των nforce2 και έχει σχεδόν λυθεί. Δε με πιστεύετε; Η nvidia έβγαλε ένα γενικό bios για όλες τις μητρικές με το τσιπάκι της που βελτιώνουν τη σταθερότητα και τις επιδόσεις. Η Asus ήδη έβγαλε ένα δικό της που βασίζεται σε αυτό της nvidia και το οποίο ΛΕΝΕ οτι επιτρέπει σχεδόν σε όλες τις A7N8X να πιάσουν τα 200ΜHz.

 

ʼσχετο αλλά μιας και μίλησα για updates του nforce. Βγαίνουν όπου να'ναι καινούργιοι drivers για το nforce2. Οπότε όσοι είστε για format(εγώ) κάντε λίγο υπομονή για να βάλετε την τελευταία έκδοση...

Και μια απορία βρε paravatis. Πως και δεν είχες διαγνώσει πρόβλημα σε ένα τόσο νευραλγικό σημείο(μνήμη-μητρική) νωρίτερα απο 3 μηνές μετά την αγορά;
