Asus p4p800 e compatibilità ram

[nicot]

Come ho fatto?
Le ho messe a 220 e vanno.
V 1.85
Su asus p4p800Dlx
In realtà ho nontato segni di instabilità a 220 (qualche superpi non finito) mentre a 217 (pc3500) non hanno nessun problema.

Ragazzi...giusto per informazione, volevo rendervi partecipi della disponibilità e qualità dell'assistenza Kingston!
Gli ho scritto tramite la sezione di assistenza del sito, e dopo poche ore mi hanno risposto, vi copio qui la discussione, anche perchè parla proprio dei problemi appunto qui discussi...
...non fate caso perfavore al mio orribile inglese!

MIA MAIL:

I've got a KHX3200K2/512, I've tried to run that ram at 2-2-2-6 but it was very unstable, and I've got a lot of blue screen on windows XP, with various errors, such "page fault in nonpaged area" and others.
Now I'm using the setting 2-3-3-6 and the system seems to be stable, but I'm not very happy to set my ram at that timings, if the specific say 2-2-2-6.

I've got a Asus P4P800 with a P4 2.6Ghz FSB 800 and the memory acceleration mode in bios is still disabled, for this testing.


RISPOSTA:

The following are some troubleshooting hints that might help solve the
issues with the memory.

The performance and compatibility of a motherboard is dependent on its
various components. Due to the variation of components used on generic
motherboards, compatibility problems may occur especially should the
specifications [i.e. the memory timings] exceed the requirements the board
is designed and built for. Motherboards resemble the interface of a system
on which all components communicate with each other. The time it takes an
electric signal to get from a hardware component to it's controller and
vice versa is essential and modification of the timings can affect the
stability of the whole system as other controllers and devices also
communicate with this controller. Therefore, when overclocking and thus
applying timings that the board and different components are not designed
for, the whole clock cycle of a system is affected and the timings have to
be individually modified to find a stable setting.

If you experience memory related stability problems it could be due to
memory timings being too aggressive for your current configuration. For
example we recommend to disable/change any top performance, turbo or
similar presets for the memory to a standard value, as they are meant as a
final optimization of system access timings and not for general usage.
Should you require more information about the above-mentioned settings
please consult the system/motherboard manufacturer. In case you have
configured the memory timings to be set by the SPD this could cause a
problem as the timings in the SPD are set to 2-2-2-6-1 for the
KHX3200K2/***, however the required voltage of 2.6V+, in some cases even
above 2.75V, on specific motherboards has to be configured manually in
order to enable it to run the memory at these timings.

Please also be aware that according to our information the Canterwood and
Springdale boards require a RAS to CAS delay of at least 3 and a RAS to CAS
of 2 will not work.

Modifying the voltage in a system and running the components at timings
that exceed the specifications i.e. of the motherboard is also known as
overclocking and Kingston cannot recommend this as it breaches standard
motherboard component specification. This is why we generally suggest to
use only the memory modules that we have listed on our website at
http://www.kingston.com/products/default.asp for a specific motherboard, as
they match the specifications the manufacturer has released for the
motherboard.

In certain cases additional cooling of the motherboard might also be
required to improve stability of the system. Try pointing a fan at the
motherboard and see if that improves the stability at the desired timings.
If yes we recommend installing North- and Southbridge fans and heat sinks.

We also recommend upgrading the BIOS to the latest revision on the
motherboard should you experience problems. Please contact the manufacturer
of the motherboard for further help on memory compatibility and how to
update your BIOS and configure it to run the memory at the desired speed
with specific timings.

E brava Kingston!
Almeno per l'assistenza...
In effetti se si va a vedere sul loro sito, per la P4P800 sono elencate tutte le KVR, ma delle HyperX non ce n'è traccia!
E poi loro stessi dicono di provare ad alzare il voltaggio standard....ma allora non è standard un piffero
E poi dicono che gli Springdale e i Canterwood, con un RAS to CAS a 2.....non vanno! Mah....e poi tra l'altro qua c'è chi comunque a 2 invece ci va...
Ci capisco sempre meno in tutta questa storia!
