Desktops can use the drivers from AMD. It is separate hardware and not customized by Dell.

However be aware that windows 7 is no longer supported by Microsoft. Time to buy a new computer that can be safely used on the internet.

Hi @tonigau,

You might consider a GT 1030 GDDR5 for a GPU.  It's commonly recommended by one of our Rockstar's for various Optiplex's.  You'll need the low profile version if you have a DT or SFF.

What size is your 990 - MT, DT, or SFF?  If you had the USFF, you wouldn't be able to add a GPU card.

Image will show once approved by a moderator:

Don't know if you missed it - But according to an article speedstep linked in another thread, nobody has suffered from spectre and meltdown.

BIOS should be up to date (with the latest version for that model) as that also helps with security issues and recognizing newer hardware.

Yes, but what about spectre and meltdown?

A 990 can still run Win10.

Win7 drivers work fine with 10 but 10 is not supported on this model.

You move the downloaded file from downloads to the My Documents folder.

You then extract the contents of the cab file using 7zip.

https://www.7-zip.org/download.html

You then update any Yellow ! in device manager with the update from my pc instead of the internet.

Intel and other vendors have indicated that they wont't patch for this.

" nobody has suffered from spectre and meltdown". That statement is absolute nonsense or very bad advice. With billions of users there is a possibility that Spectre and Meltdown will be used to steal data.  Its not malware infection its man in the middle data leak.  Its not a virus infection its stealing data from your pc and sending to an attacker.

So you would never know if you were affected until its too late.

Meltdown was issued a Common Vulnerabilities and Exposures ID of CVE - 2017-5754

• Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5753, Important, S390, x86, and x86-64)
• Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5715, Important, S390)

• Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. (CVE-2017-5754, Important, x86-64)

BIOS A24 is listed as URGENT update.

so you and 40% of the world are running w7 still,  ok.

so what stops you , your posts are not clear on that.?

and AMD does not support your card on w10 at all, HD5000 up; below no.

HD3450 here it is  at AMD.com  (and at dell)

why not try,  you nor the PC will blow up, (not hot swapped that is)

what stops you? IDK, so much fear over one card.   Dell offers cards based on not what works only but what is best for class of users, of THAT PC, so means zero what reallyworks.

load your now DOA , W7 OS, see Pnp does work

then try the newest AMD.com driver next click W7 , get it run it.  see it does work even back to 2007 now 13 long years of working great no kidding.

? brave up>?

load w10 64bit for free and get a real GPU car GTX7xx up. dump  that relic AMD card

or get  HD5xxx card up. they do run w10 .

w10-64  even runs on 380 dell .  optiplex and other PCs back to 2005, (have proof)

but this is what  fails. on many for w10

sound chip dead, buy $4 dongle be happy USB dongle

get  better GPU card. the iGPU HD2000 has no w10 support on gen 2 CPU. but screen does work.

you have Q67 Express Chipset, and gen2 CPU,  and does run ok,.  just some things can fail, minor.

love how dells spec page forgets to tell what sound chip is in the PC, wow. but  the driver tells me what it is.

Realtek ALC269 High Definition Audio Driver 2013 last driver ever,. from dell.  and not w10 supported.

but it might work if you learn the crafty skill loading w7 drivers to w10 using  magic Compatibility mode, ask.

good luck but why not try w10 first then ask for help, next,  w10 upgrades over w7 for free now.

MS changing rules,  all the time but is good to try, that, first. do the upgrade.

MS wants to end w7 forever and did, zero support now. w7, the end is now.

just 40% more go.... and bingo. (yes 2005 to 2020 PC only) yes.

"With billions of users there is a possibility that Spectre and Meltdown will be used to steal data."

@speedstep,

Yes speedstep, I thought you might say something about that.  You state the possibility, yet there's no confirmed cases.  That may be something to state along with stating the possibilities.  It's nonsense or bad advice to not to.

"You state the possibility, yet there's no confirmed cases. That may be something to state along with stating the possibilities."

Since this is a data breach not malware or something that resides on your PC how do you validate that nobody has lost data from this attack?  This is not my statement or warning it comes from DELL and Microsoft and NVIDIA and AMD etc. Client systems used in browser scenarios such as workstations or terminal servers are at increased risk of these vulnerabilities.

Dell, Intel, NVIDIA,  ATI etc all say its a HIGH on the scale.

CVE warnings are not issued lightly.

Telling people not to worry about it is nonsense.

This is a major vulnerability in processor chips with manufacturers confirming several variants affecting multiple  hardware implementations, dubbed “Meltdown” and “Spectre”.  Its not limited to windows it applies to Macos and Linux and Windows etc.

Hardware vulnerabilities (known as Spectre and Meltdown) involving speculative execution side channels that affect AMD, ARM, and Intel CPUs

• Windows Client Guidance for IT Pros to protect against speculative execution side-channel vulnerabilities
• Windows Server guidance to protect against speculative execution side-channel vulnerabilities

Both can be described as “side channel” attacks which allow attackers to steal passwords, customer data, IP and more stored in the memory of programs running on a victim’s machine.
